The Gromov-Hausdorff distance between spheres.<br />
<br />
The Gromov-Hausdorff distance is a fundamental tool in Riemanian geometry (through the topology it generates) and is also utilized in applied geometry and topological data analysis as a metric for expressing the stability of methods which process geometric data (e.g. hierarchical clustering and persistent homology barcodes via the Vietoris-Rips filtration). In fact, distances such as the Gromov-Hausdorff distance or its Optimal Transport variants (i.e. the so-called Gromov-Wasserstein distances) are nowadays often invoked in applications related to data classification.<br />
<br />
Whereas it is often easy to estimate the value of the Gromov-Hausdorff distance between two given metric spaces, its ''precise'' value is rarely easy to determine. Some of the best estimates follow from considerations related to both the stability of persistent homology and to Gromov's filling radius. However, these turn out to be non-sharp.<br />
<br />
In this talk, I will describe these estimates and also results which permit calculating the precise value of the Gromov-Hausdorff between pairs of spheres (endowed with their usual geodesic distance). These results involve lower bounds which arise from a certain version of the Borsuk-Ulam theorem that is applicable to discontinuous maps, and also matching upper bounds which are induced from specialized constructions of (a posteriori optimal) ``correspondences" between spheres.<br />

Title: How curved is a combinatorial graph?<br />
<br />
Abstract: Curvature is one of the fundamental ingredients in differential geometry. People are increasingly interested in whether it is possible to think of combinatorial graphs as behaving like manifolds and a number of different notions of curvature have been proposed. I will introduce some of the existing ideas and then propose a new notion based on a simple and explicit linear system of equations that is easy to compute. This notion satisfies a surprisingly large number of desirable properties -- connections to game theory (especially the von Neumann Minimax Theorem) and potential theory will be sketched; simultaneously, there is a certain "magic" element to all of this that is poorly understood and many open problems remain. I will also sketch some curious related problems that remain mostly open. No prior knowledge of differential geometry (or graphs) is required.<br />

Title: Surfaces and foliations in hyperbolic 3-manifolds<br />
<br />
Abstract: How does the geometric theory of hyperbolic 3-manifolds interact with the topological theory of foliations within them? Both points of view have seen profound developments over the past 40 years, and yet we have only an incomplete understanding of their overlap. I won't have much to add to this understanding! Instead, I will meander through aspects of both stories, saying a bit about what we know and pointing out some interesting questions.<br />

Title: End-periodic maps, via fibered 3-manifolds<br />
<br />
Abstract: In the second lecture I will focus on some joint work with Michael Landry and Sam Taylor. Thurston showed how a certain ``spinning<nowiki>''</nowiki> construction in a fibered 3-manifold produces a depth-1 foliation, which is described by an end-periodic map of an infinite genus surface. The dynamical properties of such maps were then studied by Handel-Miller, Cantwell-Conlon-Fenley and others. We show how to reverse this construction, obtaining every end-periodic map from spinning in a fibered manifold. This allows us to recover the dynamical features of the map, and more, directly from the more classical theory of fibered manifolds.<br />

'''Title''': Boundaries, boundaries, and more boundaries <br />
<br />
'''Abstract:''' It is possible to learn a lot about a group by studying how it acts on various metric spaces. One particularly interesting (and ubiquitous) class of groups are those that act nicely on negatively curved spaces, called hyperbolic groups. Since their introduction by Gromov in the 1980s, hyperbolic groups and their generalizations have played a central role in geometric group theory. One fruitful tool for studying such groups is their boundary at infinity. In this talk, I will discuss two generalizations of hyperbolic groups, relatively hyperbolic groups and hierarchically hyperbolic groups, and describe boundaries of each. I will describe various relationships between these boundaries and explain how the hierarchically hyperbolic boundary characterizes relative hyperbolicity among hierarchically hyperbolic groups. This is joint work with Jason Behrstock and Jacob Russell. <br />

Title: Mathematics: A key to climate research<br />
<br />
Abstract: Mathematics in climate research is often thought to be mainly a provider of techniques for solving, e.g., the atmosphere and ocean flow equations. Three examples elucidate that its role is much broader and deeper:<br />
<br />
1) Climate modelers often employ reduced forms of “the flow equations” for efficiency. Mathematical analysis helps assessing the regimes of validity of such models and defining conditions under which they can be solved robustly.<br />
<br />
2) Climate is defined as “weather statistics”, and climate research investigates its change in time in our “single realization of Earth” with all its complexity. The required reliable notions of time dependent statistics for sparse data in high dimensions, however, remain to be established. Recent mathematical research offers advanced data analysis techniques that could be “game changing” in this respect.<br />
<br />
3) Climate research, economy, and the social sciences are to generate a scientific basis for informed political decision making. Subtle misunderstandings often hamper systematic progress in this area. Mathematical formalization can help structuring discussions and bridging language barriers in interdisciplinary research.<br />

Title: Embedded solitary internal waves<br />
<br />
Abstract: The ocean and atmosphere are density stratified fluids.<br />
Stratified fluids with narrow regions of rapid density variation with<br />
respect to depth (pycnoclines) are often modelled as layered flows. In<br />
this talk we shall examine horizontally propagating internal waves<br />

oscillatory vertical structure. Mode-2 nonlinear waves (typically)<br />
occur within the linear spectrum of mode-1 waves (i.e. they travel at<br />
lower speeds than mode-1 waves), and are hence generically associated<br />
with an unphysical resonant mode-1 oscillatory tail. We will present<br />
evidence that these tail oscillations can be found to have zero<br />
amplitude, thus resulting in families of localised solutions (so<br />
called embedded solitary waves) in the Euler equations. This is the<br />
first example we know of embedded solitary waves in the Euler<br />
equations.<br />

Title: Flow and friction on a beach due to breaking waves<br />
<br />
Abstract: As water waves approach a beach, they undergo dramatic<br />
transformations that have significant consequences for beach<br />
morphology. The most important transformations for the flow dynamics<br />
are that waves usually break before they reach the shoreline and that<br />
their height collapses when they do reach the shoreline. In this talk,<br />
we consider these processes and the subsequent flow that is driven up<br />
the beach. We present measurements of this flow in large-scale<br />
experiments with a focus on understanding the flow evolution in space<br />
and time, its friction with the beach surface, and its potential to<br />
transport large amounts of sediment. We demonstrate the link between<br />
wave-driven flow on a beach and canonical solutions to the shallow<br />
water equations, which allows us to describe the flow using<br />
reduced-parameter models. Using measurements of the wall shear stress,<br />
we also show that the importance of friction is confined to a narrow<br />
region within the flow at the interface between the wet and dry<br />
portions of the beach, and we present a simplified model that<br />
considers the dynamics of this region. Finally, we discuss a few<br />
extensions of this work that have applications to understanding<br />
sediment transport and the risk of coastal flooding.<br />

Title: Quantum information for simulation of classical dynamics<br />
<br />
Abstract: We present a framework for simulating classical dynamical systems by finite-dimensional quantum system amenable to implementation on a quantum computer. Using ideas from kernel-based machine learning, the framework employs a quantum feature map for representing classical states by density operators on a reproducing kernel Hilbert space (RKHS). Simultaneously, a mapping is employed to represent classical observables by quantum observables on the RKHS such that quantum mechanical expectation values are consistent with pointwise function evaluation. With this approach, quantum states and observables evolve under the Koopman operator of the dynamical system in a consistent manner with classical evolution. Moreover, the state of the quantum system can be projected onto a finite-rank density operator on a tensor product Hilbert space, enabling efficient implementation in a quantum circuit. We illustrate our approach with quantum circuit simulations of low-dimensional dynamical systems, as well as actual experiments on the IBM Quantum System One.<br />

Title: Optimization in theory and practice<br />
<br />
Abstract: Complexity analysis in optimization seeks upper bounds on<br />
the amount of work required to find approximate solutions of problems<br />
in a given class with a given algorithm, and also lower bounds,<br />
usually in the form of a worst-case example from a given problem<br />
class. The relationship between theoretical complexity bounds and<br />
practical performance of algorithms on “typical” problems varies<br />
widely across problem and algorithm classes. Over the years, research<br />
emphasis has switched between the theoretical and practical aspects of<br />
algorithm design and analysis. This<br />
talk surveys complexity analysis and its relationship to practice in<br />
optimization, with an emphasis on linear programming and convex and<br />
nonconvex nonlinear optimization, providing historical (and cultural)<br />
perspectives on research in these areas.<br />

Title: Theory and observations that slow tropical motions transport latent energy poleward<br />
<br />
Abstract: Interactions between large-scale waves and the Hadley Cell are examined using a linear two-layer model on an $f$-plane. A linear meridional moisture gradient determines the strength of the idealized Hadley cell. The trade winds are in thermal wind balance with a weak temperature gradient (WTG). The domain is in WTG balance and wave solutions take the form of moisture modes. The westward propagation of the waves is largely due to moisture advection by the trade winds. Meridional moisture advection renders them unstable, i.e. they grow from ``moisture-vortex instability". The instability results in a poleward eddy moisture flux that flattens the mean meridional moisture gradient, thereby weakening the Hadley Cell. A Hadley Cell-moisture mode interaction is found that is reminiscent of quasi-geostrophic wave-mean flow interactions, except that wave activity is due to column moisture variance rather than potential vorticity variance. WTG balance reduces the Lorenz energy cycle to kinetic energy generation and conversions between the mean flow and the eddies. The conversion of zonal mean kinetic energy to eddy kinetic energy is due to the poleward eddy moisture flux and hence the tendency in wave activity. Data from ERA5 shows that tropical depression-like waves ---which were previously identified to behave like moisture modes that grow from moisture-vortex instability-- and flux moisture poleward. An analogy is proposed in which moisture modes are the tropical analog to midlatitude baroclinic waves. Moisture-vortex instability is analogous to baroclinic instability, stirring latent energy in the same way that baroclinic eddies stir sensible heat.<br />

Title: Flows about superhydrophobic surfaces<br />
<br />
Abstract: Superhydrophobic surfaces, formed by air entrapment within the cavities of hydrophobic solid substrates, offer a promising potential for hydrodynamic drag reduction. In several of the prototypical surface geometries the flows are two-dimensional, governed by Laplace’s equation in the longitudinal problem and the biharmonic equation in the transverse problem. Moreover, low-drag configurations are typically associated with singular limits. Thus, the analysis of liquid slippage past superhydrophobic surfaces naturally invites the use of both singular-perturbation methods and conformal-mapping techniques. I will discuss the combined application of these methodologies to several emerging problems in the field.<br />

Title: Swimming and burrowing in sand and water<br />
<br />
Abstract: Organisms ranging from bacteria to reptiles can be found in granular beds which are often flooded with water and other matter. Depending on their size and strength, they may move entirely within the pore space or rearrange the material locally in search of food and shelter. We will discuss the dynamics of limbless worm Lumbriculus variegatus as a model to understand evolution-based strategies developed by organisms which routinely live and move through such disordered porous environments. The worms are shown to employ elongation-contraction and transverse undulatory strokes to propel themselves through a wide range of mediums. Our analysis in terms of the rheology of the medium shows that the dual strokes can be used by active intruders to move effectively from water through the loose fluidizable surface layers to the well-consolidated bed below. We will demonstrate corresponding motion of magnetoelastic robots depending on the frequency of their undulatory strokes and body elasticity. We will then examine worm foraging in the porous medium modeled as a series of chambers connected by narrow passages where steric interactions with confining walls lead to significant barriers for transport. Their escape time as they collide with the boundaries and locate passages between the chambers will be discussed in terms of a boundary-following random walk model.<br />

Title: Mathematics: A key to climate research<br />
<br />
Abstract: Mathematics in climate research is often thought to be mainly a provider of techniques for solving, e.g., the atmosphere and ocean flow equations. Three examples elucidate that its role is much broader and deeper:<br />
<br />
1) Climate modelers often employ reduced forms of “the flow equations” for efficiency. Mathematical analysis helps assessing the regimes of validity of such models and defining conditions under which they can be solved robustly.<br />
<br />
2) Climate is defined as “weather statistics”, and climate research investigates<br />
its change in time in our “single realization of Earth” with all its complexity. The required reliable notions of time dependent statistics for sparse data in high dimensions, however, remain to be established. Recent mathematical research offers advanced data analysis techniques that could be “game changing” in this respect.<br />
<br />
3) Climate research, economy, and the social sciences are to generate a scientific basis for informed political decision making. Subtle misunderstandings often hamper systematic progress in this area. Mathematical formalization can help structuring discussions and bridging language barriers in interdisciplinary research.</div>Stechmannhttps://wiki.math.wisc.edu/index.php?title=Applied/ACMS/absS23&diff=24678Applied/ACMS/absS232023-03-21T13:38:26Z<p>Stechmann: /* ACMS Abstracts: Spring 2023 */</p>

Title: Embedded solitary internal waves<br />
<br />
Abstract: The ocean and atmosphere are density stratified fluids.<br />
Stratified fluids with narrow regions of rapid density variation with<br />
respect to depth (pycnoclines) are often modelled as layered flows. In<br />
this talk we shall examine horizontally propagating internal waves<br />
within a three-layer fluid, with a focus on mode-2 waves which have<br />
oscillatory vertical structure. Mode-2 nonlinear waves (typically)<br />
occur within the linear spectrum of mode-1 waves (i.e. they travel at<br />

Title: Embedded solitary internal waves<br />
<br />
Abstract: The ocean and atmosphere are density stratified fluids.<br />
Stratified fluids with narrow regions of rapid density variation with<br />
respect to depth (pycnoclines) are often modelled as layered flows. In<br />
this talk we shall examine horizontally propagating internal waves<br />
within a three-layer fluid, with a focus on mode-2 waves which have<br />
oscillatory vertical structure. Mode-2 nonlinear waves (typically)<br />
occur within the linear spectrum of mode-1 waves (i.e. they travel at<br />
lower speeds than mode-1 waves), and are hence generically associated<br />
with an unphysical resonant mode-1 oscillatory tail. We will present<br />
evidence that these tail oscillations can be found to have zero<br />
amplitude, thus resulting in families of localised solutions (so<br />
called embedded solitary waves) in the Euler equations. This is the<br />
first example we know of embedded solitary waves in the Euler<br />
equations.<br />

Title: Flow and friction on a beach due to breaking waves<br />
<br />
Abstract: As water waves approach a beach, they undergo dramatic<br />
transformations that have significant consequences for beach<br />
morphology. The most important transformations for the flow dynamics<br />
are that waves usually break before they reach the shoreline and that<br />
their height collapses when they do reach the shoreline. In this talk,<br />
we consider these processes and the subsequent flow that is driven up<br />
the beach. We present measurements of this flow in large-scale<br />
experiments with a focus on understanding the flow evolution in space<br />
and time, its friction with the beach surface, and its potential to<br />
transport large amounts of sediment. We demonstrate the link between<br />
wave-driven flow on a beach and canonical solutions to the shallow<br />
water equations, which allows us to describe the flow using<br />
reduced-parameter models. Using measurements of the wall shear stress,<br />
we also show that the importance of friction is confined to a narrow<br />
region within the flow at the interface between the wet and dry<br />
portions of the beach, and we present a simplified model that<br />
considers the dynamics of this region. Finally, we discuss a few<br />
extensions of this work that have applications to understanding<br />
sediment transport and the risk of coastal flooding.<br />

Title: Quantum information for simulation of classical dynamics<br />
<br />
Abstract: We present a framework for simulating classical dynamical systems by finite-dimensional quantum system amenable to implementation on a quantum computer. Using ideas from kernel-based machine learning, the framework employs a quantum feature map for representing classical states by density operators on a reproducing kernel Hilbert space (RKHS). Simultaneously, a mapping is employed to represent classical observables by quantum observables on the RKHS such that quantum mechanical expectation values are consistent with pointwise function evaluation. With this approach, quantum states and observables evolve under the Koopman operator of the dynamical system in a consistent manner with classical evolution. Moreover, the state of the quantum system can be projected onto a finite-rank density operator on a tensor product Hilbert space, enabling efficient implementation in a quantum circuit. We illustrate our approach with quantum circuit simulations of low-dimensional dynamical systems, as well as actual experiments on the IBM Quantum System One.<br />

Title: Optimization in theory and practice<br />
<br />
Abstract: Complexity analysis in optimization seeks upper bounds on<br />
the amount of work required to find approximate solutions of problems<br />
in a given class with a given algorithm, and also lower bounds,<br />
usually in the form of a worst-case example from a given problem<br />
class. The relationship between theoretical complexity bounds and<br />
practical performance of algorithms on “typical” problems varies<br />
widely across problem and algorithm classes. Over the years, research<br />
emphasis has switched between the theoretical and practical aspects of<br />
algorithm design and analysis. This<br />
talk surveys complexity analysis and its relationship to practice in<br />
optimization, with an emphasis on linear programming and convex and<br />
nonconvex nonlinear optimization, providing historical (and cultural)<br />
perspectives on research in these areas.<br />

Title: Theory and observations that slow tropical motions transport latent energy poleward<br />
<br />
Abstract: Interactions between large-scale waves and the Hadley Cell are examined using a linear two-layer model on an $f$-plane. A linear meridional moisture gradient determines the strength of the idealized Hadley cell. The trade winds are in thermal wind balance with a weak temperature gradient (WTG). The domain is in WTG balance and wave solutions take the form of moisture modes. The westward propagation of the waves is largely due to moisture advection by the trade winds. Meridional moisture advection renders them unstable, i.e. they grow from ``moisture-vortex instability". The instability results in a poleward eddy moisture flux that flattens the mean meridional moisture gradient, thereby weakening the Hadley Cell. A Hadley Cell-moisture mode interaction is found that is reminiscent of quasi-geostrophic wave-mean flow interactions, except that wave activity is due to column moisture variance rather than potential vorticity variance. WTG balance reduces the Lorenz energy cycle to kinetic energy generation and conversions between the mean flow and the eddies. The conversion of zonal mean kinetic energy to eddy kinetic energy is due to the poleward eddy moisture flux and hence the tendency in wave activity. Data from ERA5 shows that tropical depression-like waves ---which were previously identified to behave like moisture modes that grow from moisture-vortex instability-- and flux moisture poleward. An analogy is proposed in which moisture modes are the tropical analog to midlatitude baroclinic waves. Moisture-vortex instability is analogous to baroclinic instability, stirring latent energy in the same way that baroclinic eddies stir sensible heat.<br />

Title: Flows about superhydrophobic surfaces<br />
<br />
Abstract: Superhydrophobic surfaces, formed by air entrapment within the cavities of hydrophobic solid substrates, offer a promising potential for hydrodynamic drag reduction. In several of the prototypical surface geometries the flows are two-dimensional, governed by Laplace’s equation in the longitudinal problem and the biharmonic equation in the transverse problem. Moreover, low-drag configurations are typically associated with singular limits. Thus, the analysis of liquid slippage past superhydrophobic surfaces naturally invites the use of both singular-perturbation methods and conformal-mapping techniques. I will discuss the combined application of these methodologies to several emerging problems in the field.<br />

Title: Swimming and burrowing in sand and water<br />
<br />
Abstract: Organisms ranging from bacteria to reptiles can be found in granular beds which are often flooded with water and other matter. Depending on their size and strength, they may move entirely within the pore space or rearrange the material locally in search of food and shelter. We will discuss the dynamics of limbless worm Lumbriculus variegatus as a model to understand evolution-based strategies developed by organisms which routinely live and move through such disordered porous environments. The worms are shown to employ elongation-contraction and transverse undulatory strokes to propel themselves through a wide range of mediums. Our analysis in terms of the rheology of the medium shows that the dual strokes can be used by active intruders to move effectively from water through the loose fluidizable surface layers to the well-consolidated bed below. We will demonstrate corresponding motion of magnetoelastic robots depending on the frequency of their undulatory strokes and body elasticity. We will then examine worm foraging in the porous medium modeled as a series of chambers connected by narrow passages where steric interactions with confining walls lead to significant barriers for transport. Their escape time as they collide with the boundaries and locate passages between the chambers will be discussed in terms of a boundary-following random walk model.<br />

Title: Wasow Lecture: Mathematics: A key to climate research<br />
<br />
Abstract: Mathematics in climate research is often thought to be mainly a provider of techniques for solving, e.g., the atmosphere and ocean flow equations. Three examples elucidate that its role is much broader and deeper:<br />
<br />
1) Climate modelers often employ reduced forms of “the flow equations” for efficiency. Mathematical analysis helps assessing the regimes of validity of such models and defining conditions under which they can be solved robustly.<br />
<br />
2) Climate is defined as “weather statistics”, and climate research investigates<br />
its change in time in our “single realization of Earth” with all its complexity. The required reliable notions of time dependent statistics for sparse data in high dimensions, however, remain to be established. Recent mathematical research offers advanced data analysis techniques that could be “game changing” in this respect.<br />
<br />
3) Climate research, economy, and the social sciences are to generate a scientific basis for informed political decision making. Subtle misunderstandings often hamper systematic progress in this area. Mathematical formalization can help structuring discussions and bridging language barriers in interdisciplinary research.</div>Stechmannhttps://wiki.math.wisc.edu/index.php?title=Applied/ACMS/absS23&diff=24673Applied/ACMS/absS232023-03-21T13:33:46Z<p>Stechmann: /* ACMS Abstracts: Spring 2023 */</p>

Moreover, low-drag configurations are typically associated with singular limits. Thus, the analysis of liquid slippage past superhydrophobic surfaces naturally invites the use of both singular-perturbation methods and conformal-mapping techniques. I will discuss the combined application of these methodologies to several emerging problems in the field.<br />

Title: Swimming and burrowing in sand and water<br />
<br />
Abstract: Organisms ranging from bacteria to reptiles can be found in granular beds which are often flooded with water and other matter. Depending on their size and strength, they may move entirely within the pore space or rearrange the material locally in search of food and shelter. We will discuss the dynamics of limbless worm Lumbriculus variegatus as a model to understand evolution-based strategies developed by organisms which routinely live and move through such disordered porous environments. The worms are shown to employ elongation-contraction and transverse undulatory strokes to propel themselves through a wide range of mediums. Our analysis in terms of the rheology of the medium shows that the dual strokes can be used by active intruders to move effectively from water through the loose fluidizable surface layers to the well-consolidated bed below. We will demonstrate corresponding motion of magnetoelastic robots depending on the frequency of their undulatory strokes and body elasticity. We will then examine worm foraging in the porous medium modeled as a series of chambers connected by narrow passages where steric interactions with confining walls lead to significant barriers for transport. Their escape time as they collide with the boundaries and locate passages between the chambers will be discussed in terms of a boundary-following random walk model.<br />

Title: Wasow Lecture: Mathematics: A key to climate research<br />
<br />
Abstract: Mathematics in climate research is often thought to be mainly a provider of techniques for solving, e.g., the atmosphere and ocean flow equa- tions. Three examples elucidate that its role is much broader and deeper:<br />
<br />
1) Climate modelers often employ reduced forms of “the flow equations” for efficiency. Mathematical analysis helps assessing the regimes of validity of such models and defining conditions under which they can be solved robustly.<br />
<br />
2) Climate is defined as “weather statistics”, and climate research investigates<br />
its change in time in our “single realization of Earth” with all its complexity. The required reliable notions of time dependent statistics for sparse data in high dimensions, however, remain to be established. Recent math- ematical research offers advanced data analysis techniques that could be “game changing” in this respect.<br />
<br />
3) Climate research, economy, and the social sciences are to generate a scientific basis for informed political decision making. Subtle misunderstandings often hamper systematic progress in this area. Mathematical for- malization can help structuring discussions and bridging language barriers in interdisciplinary research.</div>Stechmannhttps://wiki.math.wisc.edu/index.php?title=Applied/ACMS&diff=24672Applied/ACMS2023-03-21T13:31:03Z<p>Stechmann: /* Spring 2023 */</p>

'''On surface homeomorphisms'''<br />
<br />
In the 1970s, Thurston generalized the classification of self-maps of the torus to surfaces of higher genus, thus completing the work initiated by Nielsen. This is known as the Nielsen-Thurston Classification Theorem. Over the years, many alternative proofs have been obtained, using different aspects of surface theory. In this talk, I will overview the classical theory and sketch the ideas of a new proof, one that offers new insights into the hyperbolic geometry of surfaces. This is joint work with Camille Horbez.<br />

'''Incidences and line counting: from the discrete to the fractal setting'''<br />
<br />
How many lines are spanned by a set of planar points?. If the points are collinear, then the answer is clearly "one". If they are not collinear, however, several different answers exist when sets are finite and "how many" is measured by cardinality. I will discuss a bit of the history of this problem and present a recent extension to the continuum setting, obtained in collaboration with T. Orponen and H. Wang. No specialized background will be assumed.<br />

'''Dependent Stopping Times and an Application to Credit Risk Theory'''<br />
<br />
Stopping times are used in applications to model random arrivals. A standard assumption in many models is that the stopping times are conditionally independent, given an underlying filtration. This is a widely useful assumption, but there are circumstances where it seems to be unnecessarily strong. In the first part of the talk, we use a modified Cox construction, along with the bivariate exponential introduced by Marshall & Olkin (1967), to create a family of stopping times, which are not necessarily conditionally independent, allowing for a positive probability for them to be equal. We also present a series of results exploring the special properties of this construction.<br />
<br />
In the second part of the talk, we present an application of our model to Credit Risk. We characterize the probability of a market failure which is defined as the default of two or more globally systemically important banks (G-SIBs) in a small interval of time. The default probabilities of the G-SIBs are correlated through the possible existence of a market-wide stress event. We derive various theorems related to market failure probabilities, such as the probability of a catastrophic market failure, the impact of increasing the number of G-SIBs in an economy, and the impact of changing the initial conditions of the economy's state variables. We also show that if there are too many G-SIBs, a market failure is inevitable, i.e., the probability of a market failure tends to one as the number of G-SIBs tends to infinity.<br />

'''The search for special symmetries'''<br />
<br />
What are the canonical sets of symmetries of n-dimensional space? I'll describe the history of this question, going back to Schwarz, Fuchs, Painlevé, and others, and some new answers to it, obtained jointly with Aaron Landesman. While our results rely on low-dimensional topology, Hodge theory, and the Langlands program, and we'll get a peek into how these areas come into play, no knowledge of them will be assumed.<br />

'''Constructing isometric tori with the same curvatures'''<br />
<br />
Which data determine an immersed surface in Euclidean three-space up to rigid motion? A generic surface is locally determined by only an intrinsic metric and extrinsic mean curvature function. However, there are exceptions. These may arise in a family like the isometric family of vanishing mean curvature surfaces transforming a catenoid into a helicoid.<br />
<br />
For compact surfaces, Lawson and Tribuzy proved in 1981 that a metric and non-constant mean curvature function determine at most one immersion with genus zero, but at most two compact immersions (compact Bonnet pairs) for higher genus. In this talk, we discuss our recent construction of the first examples of compact Bonnet pairs. It uses a local classification by Kamberov, Pedit, and Pinkall in terms of isothermic surfaces. Moreover, we describe how a structure-preserving discrete theory for isothermic surfaces and Bonnet pairs led to this discovery.<br />
<br />
The smooth theory is joint work with Alexander Bobenko and Tim Hoffmann and the discrete theory is joint work with Tim Hoffmann and Max Wardetzky.<br />

''Note the unusual time and room!''<br />
<br />
'''An introduction to counts-of-counts data'''<br />
<br />
Counts-of-counts data arise in many areas of biology and medicine, and have been studied by statisticians since the 1940s. One of the first examples, discussed by R. A. Fisher and collaborators in 1943 [1], concerns estimation of the number of unobserved species based on summary counts of the number of species observed once, twice, … in a sample of specimens. The data are summarized by the numbers ''C<sub>1</sub>, C<sub>2</sub>, …'' of species represented once, twice, … in a sample of size<br />
<br />
''N = C<sub>1</sub> + 2 C<sub>2</sub> + 3 C<sub>3</sub> + <sup>….</sup>'' containing ''S = C<sub>1</sub> + C<sub>2</sub> + <sup>…</sup>'' species; the vector ''C ='' ''(C<sub>1</sub>, C<sub>2</sub>, …)'' gives the counts-of-counts. Other examples include the frequencies of the distinct alleles in a human genetics sample, the counts of distinct variants of the SARS-CoV-2 S protein obtained from consensus sequencing experiments, counts of sizes of components in certain combinatorial structures [2], and counts of the numbers of SNVs arising in one cell, two cells, … in a cancer sequencing experiment.<br />
<br />
In this talk I will outline some of the stochastic models used to model the distribution of ''C,'' and some of the inferential issues that come from estimating the parameters of these models. I will touch on the celebrated Ewens Sampling Formula [3] and Fisher’s multiple sampling problem concerning the variance expected between values of ''S'' in samples taken from the same population [3]. Variants of birth-death-immigration processes can be used, for example when different variants grow at different rates. Some of these models are mechanistic in spirit, others more statistical. For example, a non-mechanistic model is useful for describing the arrival of covid sequences at a database. Sequences arrive one at a time, and are either a new variant, or a copy of a variant that has appeared before. The classical Yule process with immigration provides a starting point to model this process, as I will illustrate.<br />

'''Forecast science, learn hidden networks and settle economics conjectures with combinatorics, geometry and probability.''' <br />
<br />
In many problems, one observes noisy data coming from a hidden or complex combinatorial structure. My research aims to understand and exploit such structures to arrive at an efficient and optimal solution. I will showcase a few successes, achieved with different tools, from different different fields: networks forecasting, hydrology, and auction theory. Then I will outline some open questions in each field. <br />

'''Multiscale inverse problem, from Schroedinger to Newton to Boltzmann'''<br />
<br />
Inverse problems are ubiquitous. We probe the media with sources and measure the outputs, to infer the media information. At the scale of quantum, classical, statistical and fluid, we face inverse Schroedinger, inverse Newton’s second law, inverse Boltzmann problem, and inverse diffusion respectively. The universe, however, expects a universal mathematical description, as Hilbert proposed in 1900. In this talk, we discuss the connection between these problems. We will give arguments for justifying that these are the same problem merely represented at different scales. It is a light-hearted talk, and I will mostly focus on the story instead of the derivation. PDE background is appreciated but not necessary.<br />

'''Private AI: Machine Learning on Encrypted Data'''<br />
<br />
As the world adopts Artificial Intelligence, the privacy risks are many. AI can improve our lives, but may leak our private data. Private AI is based on Homomorphic Encryption (HE), a new encryption paradigm which allows the cloud to operate on private data in encrypted form, without ever decrypting it, enabling private training and private prediction. Our 2016 ICML CryptoNets paper showed for the first time that it was possible to evaluate neural nets on homomorphically encrypted data, and opened new research directions combining machine learning and cryptography. The security of Homomorphic Encryption is based on hard problems in mathematics involving lattices, recently standardized by NIST for post-quantum cryptography. This talk will explain Homomorphic Encryption, Private AI, and explain HE in action.<br />

'''Artificial Intelligence & Cryptography: Privacy and Security in the AI era'''<br />
<br />
How is Artificial Intelligence changing your life and the world? How do you expect your data to be kept secure and private in the future? Artificial intelligence (AI) refers to the science of utilizing data to formulate mathematical models that predict outcomes with high assurance. Such predictions can be used to make decisions automatically or give recommendations with high confidence. Cryptography is the science of protecting the privacy and security of data. This talk will explain the dynamic relationship between cryptography and AI and how AI can be used to attack post-quantum cryptosystems.<br />
<br />

'''Rocket-propelled Cholesky: Addressing the challenges of large-scale kernel computations'''<br />
<br />
Kernel methods are used for prediction and clustering in many data science and scientific computing applications, but applying kernel methods to a large number of data points N is expensive due to the high cost of manipulating the N x N kernel matrix. A basic approach for speeding up kernel computations is low-rank approximation, in which we replace the kernel matrix A with a factorized approximation that can be stored and manipulated more cheaply. When the kernel matrix A has rapidly decaying eigenvalues, mathematical existence proofs guarantee that A can be accurately approximated using a constant number of columns (without ever looking at the full matrix). Nevertheless, for a long time designing a practical and provably justified algorithm to select the appropriate columns proved challenging.<br />
<br />
Recently, we introduced RPCholesky ("randomly pivoted" or "rocket-propelled" Cholesky), a natural algorithm for approximating an N x N positive semidefinite matrix using k adaptively sampled columns. RPCholesky can be implemented with just a few lines of code; it requires only (k+1)N entry evaluations and O(k^2 N) additional arithmetic operations. In experiments, RPCholesky matches or improves on the performance of alternative algorithms for low-rank psd approximation. Moreover, RPCholesky provably achieves near-optimal approximation guarantees. The simplicity, effectiveness, and robustness of this algorithm strongly support its use for large-scale kernel computations.<br />

'''From gauge theory to geometric representation theory and back'''<br />
<br />
We start from the celebrated construction (due to Grojnowski and Nakajima) of a Heisenberg algebra action on the cohomology groups of Hilbert schemes of points on surfaces<br />
<br />
# replacing Hilbert schemes with moduli spaces of higher rank sheaves yields a computation of Nekrasov partition functions in 5d supersymmetric gauge theory, and a proof of the deformed Alday-Gaiotto-Tachikawa conjecture.<br />
# replacing cohomology by Chow groups gives a proof of the Beauville conjecture in the hyperkahler geometry of Hilbert schemes of points on K3 surfaces (with Maulik)<br />
# working with derived categories allows us to construct a detailed framework realizing categorical knot invariants in terms of the geometry of Hilbert schemes of points on the affine plane (with Gorsky and Rasmussen)<br />

'''Fractal Geometry of the KPZ equation'''<br />
<br />
The Kardar-Parisi-Zhang (KPZ) equation is a fundamental stochastic PDE related to many important models like random growth processes, Burgers turbulence, interacting particles system, random polymers etc. In this talk, we focus on how the tall peaks and deep valleys of the KPZ height function grow as time increases. In particular, we will ask what is the appropriate scaling of the peaks and valleys of the (1+1)-d KPZ equation and whether they converge to any limit under those scaling. These questions will be answered via the law of iterated logarithms and fractal dimensions of the level sets. The talk will be based on joint works with Sayan Das and Jaeyun Yi. If time permits, I will also mention an interesting story about the (2+1)-d and (3+1)-d case (work in progress with Jaeyun Yi).<br />

'''Quantum algorithms for Hamiltonian simulation with unbounded operators'''<br />
<br />
Recent years have witnessed tremendous progress in developing and analyzing quantum computing algorithms for quantum dynamics simulation of bounded operators (Hamiltonian simulation). However, many scientific and engineering problems require the efficient treatment of unbounded operators, which frequently arise due to the discretization of differential operators. Such applications include molecular dynamics, electronic structure theory, quantum control and quantum machine learning. We will introduce some recent advances in quantum algorithms for efficient unbounded Hamiltonian simulation, including Trotter type splitting and the quantum highly oscillatory protocol (qHOP) in the interaction picture. The latter yields a surprising superconvergence result for regular potentials. In the end, I will discuss briefly how Hamiltonian simulation techniques can be applied to a quantum learning task achieving optimal scaling. (The talk does not assume a priori knowledge on quantum computing.)<br />

'''An approach to universality using Weyl m-functions'''<br />
<br />
In this talk I will present an approach to universality limits for orthogonal polynomials on the real line which is completely local and uses only the boundary behavior of the Weyl m-function at the point. We show that bulk universality of the Christoffel-Darboux kernel holds for any point where the imaginary part of the m-function has a positive finite nontangential limit. This approach is based on studying this problem in the more general setting of canonical systems and the realization that bulk universality for an associated matrix reproducing kernel at a point is equivalent to the fact that the corresponding m-function has normal limits at the same point. The talk is based on a joint work with Milivoje Lukic and Brian Simanek. If time permits, I will discuss some work in progress with Milivoje Lukic and Harald Woracek on rescaling limits for other<br />
<br />
universality classes.<br />

'''Non-uniqueness of Leray solutions to the forced Navier-Stokes equations'''<br />
<br />
In a seminal work, Leray demonstrated the existence of global weak solutions to the Navier-Stokes equations in three dimensions. Are Leray's solutions unique? This is a fundamental question in mathematical hydrodynamics, which we answer in the negative within the "forced" category, by exhibiting a one-parameter family of distinct Leray solutions with zero initial velocity and identical body force. This is joint work with Elia Brué and Maria Colombo.<br />

Title: A snapping singularity<br />
<br />
Abstract: I will discuss our preliminary work (with A. Dehadrai) on the focusing of kinetic energy and the amplification of various quantities during the snapping motion of the free end of a string or chain. This brief but violent event, with its remarkably large spikes in velocity, acceleration, and tension, is an essentially unavoidable feature of flexible structure dynamics, induced by generic initial and boundary conditions. We are guided by an analytical solution for a geometrically singular limit that features a finite-time singularity in other quantities. Regularization of this singularity does not arise from discretization of the continuous string equations or, equivalently, from the physical discreteness of a chain. It is instead associated with a length scale arising from the geometry of the problem, which evolves according to an anomalously slow curvature scaling.<br />

Title: Fluid–body interactions in liquid crystals: A complex variable approach<br />
<br />
Abstract: Fluid anisotropy, or direction-dependent response to deformation, can be observed in biofluids like mucus or, at a larger scale, self-aligning swarms of swimming bacteria. A model fluid used to investigate such environments is a liquid crystal. Large colloidal bodies undergo shape-dependent interactions when placed in such an environment, whilst deformable bodies like red blood cells tend to be stretched, offering a passive means of measuring cell material properties. While numerous methods exist for studying the liquid crystalline configurations and fluid–body interaction for a single body, there are exceedingly few analytical results for the interaction of two or more bodies. In this talk, we will bring the power of complex variables to bear on this problem, presenting a simple methodology to analytically solve for the interactions inside a liquid crystalline environment. This approach allows for the solution of a wide range of problems, opening the door to studying the role of body shape and orientation, liquid crystal anchoring conditions, and body deformability.<br />

Title: Predictive modeling of oscillating foil wake dynamics<br />
<br />
Abstract: Swimming and flying animals rely on the fluid around them to provide lift or thrust forces, leaving behind a distinct vortex wake in the fluid. The structure and size of the vortex wake is a blueprint of the animal’s kinematic trajectory, holding information about the forces and also the size, speed and direction of motion. This talk will introduce a bio-inspired oscillating turbine, which can be operated to generate energy from moving water through lift generation, in the same manner as flapping birds or bats. This style of turbines offers distinct benefits compared with traditional rotation-based turbines such as the ability to dynamically shift its kinematics for changing flow conditions, thus altering its wake pattern. Current efforts lie in predicting the vortex formation and dynamics of the highly structured wake such that it can be utilized towards cooperative motion within arrays of oscillating foils. Using numerical simulations, this talk will discuss efforts towards linking the fluid dynamic wake signature to the underlying foil kinematics, and investigating how that effects the energy harvesting performance of downstream foils. Two machine learning methodologies are introduced to classify, cluster and identify complex vorticity patterns and modes of energy harvesting, and inform more detailed modeling of arrays of oscillating foils.<br />

Title: Data-Driven Closure Modeling Using Derivative-free Kalman Methods<br />
<br />
Closure problems are critical in predicting complex dynamical systems, e.g., turbulence or cloud dynamics, for which numerically resolving all degrees of freedom remains infeasible in the foreseeable future. Although researchers have been advancing traditional closure models of those systems for decades, the performance of existing models is still unsatisfactory in many applications, mainly due to the limited representation power of existing models and the associated empirical calibration process. Recently, the rapid advance of machine learning techniques shows great potential for improving closure models of dynamical systems. In this talk, I will share some progress in data-driven closure modeling for complex dynamical systems. More specifically, I will demonstrate the use of derivative-free Kalman methods to learn closure models from indirect and limited amount of data. In addition to deterministic closures, examples of sparse identification of dynamical systems and the learning of stochastic closures will also be presented.<br />

Title: Vortex-gas models for 3d atmosphere and ocean turbulence<br />
<br />
Abstract: Atmospheres and oceans self-organize into coherent structures such as fronts, jets, and long-lived vortices. It is useful to model vortex dominated geophysical flows as a vortex gas, where solutions are assumed to take the form of a population of interacting vortices. There are many vortex gas models of increasing complexity for both 2d flow and for purely horizontal, so-called quasigeostrophic, 3d flow. Atmospheres and oceans, however, have small, but important vertical velocities. The smallness of the vertical velocity is due to rapid planetary rotation, quantified by a small Rossby number. The asymptotic expansion of the governing equations for planetary turbulence capture this small vertical velocity when carried to second order in the Rossby number. Here we find a find a vortex gas solution to these equations in the form of point vortices. The nonlinear dynamics of small numbers of such vortices shows complex and geophysically interesting vertical transport. This new point vortex model provides a platform to revisit in 3d the myriad problems studied with 2d point vortices, and provides a tool for modeling important processes in atmospheres and oceans.<br />

Title: Some results on inverse problems to elliptic PDEs with solution data and their implications in operator learning<br />
<br />
Abstract: In recent years, there have been great interests in discovering structures of partial differential equations from given solution data. Very promising theory and computational algorithms have been proposed for such operator learning problems in different settings. We will try to review some recent understandings of such a PDE learning problem from the perspective of inverse problems. In particularly, we will highlight a few analytical and computational understandings on learning a second-order elliptic PDE from single and multiple solutions.</div>Stechmannhttps://wiki.math.wisc.edu/index.php?title=Applied/ACMS&diff=23864Applied/ACMS2022-10-13T21:43:27Z<p>Stechmann: /* Fall 2022 */</p>

Title: Collective Cell Migration: Rigidity Transition and the Eyes of the Cell<br />
<br />
Abstract: Collective cell migration is an essential process in development, regeneration, and disease. The motion results from a physical balance of cell-generated forces, but the relationships between cell force and motion are challenging to study, because cell forces are actively generated within each cell and balanced by complicated interactions at the cell-substrate and cell-cell interfaces. In complex, multi-body physical systems such as this one, mathematical models can provide essential insights into the underlying mechanisms of collective cell force generation, transmission, and, ultimately, motion. This presentation will describe an experimentalist’s perspective on a class of models for collective cell migration based on the vertex model, wherein the cells are polygons that tesselate a two-dimensional plane. The models are discussed in the context of experiments performed by my research group to measure cell forces and velocities, which enable quantitative comparison between model predictions and experimental results. The presentation will focus on two specific examples. The first is a fluid-to-solid rigidity transition predicted by the models to depend on cell shape. The second is the experimental finding that cells align their propulsive forces with those of their neighbors, analogous to how birds within a flock or fish within a school use visual cues to for alignment. These two examples illustrate how our experiments have led to clearer understanding of the underlying factors within the cell that correspond to the different model parameters and have discovered new phenomena not yet accounted for in the recent models.<br />

Title: What networks of oscillators spontaneously synchronize?<br />
<br />
Abstract: Consider a network of identical phase oscillators with sinusoidal coupling. How likely are the oscillators to spontaneously synchronize, starting from random initial phases? One expects that dense networks of oscillators have a strong tendency to pulse in unison. But, how dense is dense enough? In this talk, we use techniques from numerical linear algebra, computational algebraic geometry, and dynamical systems to derive the densest known networks that do not synchronize and the sparsest ones that do. We will find that there is a critical network density above which spontaneous synchrony is guaranteed regardless of the network's topology, and prove that synchrony is omnipresent for random networks above a lucid threshold. This is joint work with Martin Kassabov, Steven Strogatz, and Mike Stillman.<br />

Title: The mechanics of a large pendulum chain<br />
<br />
Abstract: I’ll discuss a particular high-dimensional system that displays subtle behaviour found in the continuum limit. The only catch is that it formally shouldn’t, which raises a few questions. When is a discrete system large enough to be called continuous? When are approximate (broken) symmetries good enough to be treated like the real thing? When and why does a fluid approximation work as well as we like to assume? What does all this say about observables and the approach to equilibria? The particular system I have in mind is a large ideal pendulum chain, and it’s cousin the continuous flexible string. I propose that the pendulum chain is a perfect model system to study notoriously difficult phenomena such as vortical turbulence, waves, cascades and thermalisation, but with many fewer degrees of freedom than a three-dimensional fluid.<br />

Title: Recent Progress on Q^k Spectral Element Method: Accuracy, Monotonicity and Applications<br />
<br />
Abstract: In the literature, spectral element methods usually refer to finite element methods with high order polynomial basis. The Q^k spectral element method has been a popular high order method for solving second order PDEs, e.g., wave equations, for more than three decades, obtained by continuous finite element method with tenor product polynomial of degree k and with at least (k+1)-point Gauss-Lobatto quadrature. In this talk, I will present some brand new results of this classical scheme, including its accuracy, monotonicity (stability), and examples of using monotonicity to construct high order bound-preserving schemes in various applications including the Allen-Cahn equation coupled with an incompressible velocity field, Keller-Segel equation for chemotaxis, and nonlinear eigenvalue problem for Gross–Pitaevskii equation. 1) Accuracy: when the least accurate (k+1)-point Gauss-Lobatto quadrature is used, the spectral element method is also a finite difference (FD) scheme, and this FD scheme can sometimes be (k+2)-th order accurate for k>=2. This has been observed in practice but never proven before in terms of rigorous error estimates. We are able to prove it for linear elliptic, wave, parabolic and Schrödinger equations for Dirichlet boundary conditions. For Neumann boundary conditions, (k+2)-th order can be proven if there is no mixed second order derivative. Otherwise, only (k+3/2)-th order can be proven and some order loss is indeed observed in numerical tests. The accuracy result also applies to spectral element method on any curvilinear mesh that can be smoothly mapped to a rectangular mesh, e.g., solving a wave equation on an annulus region with a curvilinear mesh generated by polar coordinates. 2) Monotonicity: consider solving the Poisson equation, then a scheme is called monotone if the inverse of the stiffness matrix is entrywise non-negative. It is well known that second order centered difference or P1 finite element method can form an M-matrix thus they are monotone, and high order accurate schemes in general are not M-matrices thus not monotone. But there are exceptions. In particular, we have proven that the fourth order accurate FD scheme (Q^2 spectral element method) is a product of two M-matrices thus monotone for a variable coefficient diffusion operator: this is the first time that a high order accurate scheme is proven monotone for a variable coefficient operator. We have also proven the fifth order accurate FD scheme (Q^3 spectral element method) is a product of three M-matrices thus monotone for the Poisson equation: this is the first time that a fifth order accurate discrete Laplacian is proven monotone in two dimensions (all previously known high order monotone discrete Laplacian in 2D are fourth order accurate).<br />

Title:<br />
Multiscale Invertible Generative Networks for High-Dimensional Bayesian Inference<br />
<br />
Abstract:<br />
Sampling from high-dimensional posterior distributions in Bayesian inference is a long-standing challenging problem, especially when there are multiple modes in the posterior. For a wide class of Bayesian inference problems, low-dimensional coarse-scale surrogates can be constructed to approximate the original high-dimensional fine-scale problem, and we propose to train a Multiscale Invertible Generative Network (MsIGN) to learn such high-dimensional posteriors with multiscale structure. A novel prior conditioning layer is designed to bridge networks of different resolutions, enabling coarse-to-fine multi-stage training. The double KL divergence is also utilized as the loss function to avoid mode dropping. When applied to two Bayesian inverse problems, MsIGN clearly captures multiple modes in the high-dimensional posterior and approximates the posterior accurately, demonstrating superior performance compared with previous deep generative network approaches. When applied to natural image synthesis on standard datasets, MsIGN achieves the superior performance in terms of bits-per-dimension and yields great interpret-ability of its neurons in intermediate layers. This is a joint work with Shumao Zhang and Thomas Y. Hou.<br />

Title: An overview of the numerical methods in the atmospheric component of the Energy Exascale Earth System Model<br />
<br />
Abstract: I will first give an overview of modern Earth system models and how they are used to study the Earth's climate. I will then describe the DOE's Energy Exascale Earth System Model (E3SM) project, including Sandia’s role in developing the "dynamical core" of the atmospheric component model and porting to upcoming Exascale computers. The dynamical core is the component which solves the differential equations of motion in the Earth's atmosphere over the entire globe, which is then coupled to a suite of parametrizations modeling the many unresolved processes. I'll go through several of the design choices made in state-of-the-art global dynamical cores: choice of grid, choice of equation formulation and discretization methods. The underlying motivation of these choices is governed by preserving the most important properties of the continuum equations, such as conservation and geostrophic balance. In E3SM we have had good success with Hamiltonian structure preserving methods, where the equations are kept in Hamiltonian form and then discretized with appropriate numerical methods which lead to a discrete Hamiltonian system.<br />

Title: Tiny Giants - Mathematics Looks at Zooplankton<br />
<br />
Abstract: Zooplankton is an immensely diverse group of organisms occupying every corner of the oceans, seas, and freshwater bodies on earth. They form a crucial link between autotrophic phytoplankton and higher trophic levels such as crustaceans, mollusks, fish, and marine mammals. Changing water temperatures, salinities and decreasing pH values currently create monumental challenges to their well-being. A significant subgroup of zooplankton are crustaceans of sizes between 1 and 10 mm. They have extremely acute senses that allow them to navigate their surroundings, escape predators, find food and mate. In a series of works with Rudi Strickler (Department of Biological Sciences, University of Wisconsin - Milwaukee) we have investigated various behaviors of crustacean zooplankton. These include the visualization of the feeding current of the calanoid copepod Leptodiaptomus sicilis and the communication by sex pheromones in the copepod Temora longicornis. In these studies, we use tools from optics, ecology, computational fluid dynamics, and computational neuroscience.</div>Stechmannhttps://wiki.math.wisc.edu/index.php?title=Applied/ACMS&diff=22956Applied/ACMS2022-03-12T19:41:11Z<p>Stechmann: /* Spring 2022 */</p>

Title: What networks of oscillators spontaneously synchronize?<br />
<br />
Abstract: Consider a network of identical phase oscillators with sinusoidal coupling. How likely are the oscillators to spontaneously synchronize, starting from random initial phases? One expects that dense networks of oscillators have a strong tendency to pulse in unison. But, how dense is dense enough? In this talk, we use techniques from numerical linear algebra, computational algebraic geometry, and dynamical systems to derive the densest known networks that do not synchronize and the sparsest ones that do. We will find that there is a critical network density above which spontaneous synchrony is guaranteed regardless of the network's topology, and prove that synchrony is omnipresent for random networks above a lucid threshold. This is joint work with Martin Kassabov, Steven Strogatz, and Mike Stillman.<br />

Title: The mechanics of a large pendulum chain<br />
<br />
Abstract: I’ll discuss a particular high-dimensional system that displays subtle behaviour found in the continuum limit. The only catch is that it formally shouldn’t, which raises a few questions. When is a discrete system large enough to be called continuous? When are approximate (broken) symmetries good enough to be treated like the real thing? When and why does a fluid approximation work as well as we like to assume? What does all this say about observables and the approach to equilibria? The particular system I have in mind is a large ideal pendulum chain, and it’s cousin the continuous flexible string. I propose that the pendulum chain is a perfect model system to study notoriously difficult phenomena such as vortical turbulence, waves, cascades and thermalisation, but with many fewer degrees of freedom than a three-dimensional fluid.<br />

Title: Recent Progress on Q^k Spectral Element Method: Accuracy, Monotonicity and Applications<br />
<br />
Abstract: In the literature, spectral element methods usually refer to finite element methods with high order polynomial basis. The Q^k spectral element method has been a popular high order method for solving second order PDEs, e.g., wave equations, for more than three decades, obtained by continuous finite element method with tenor product polynomial of degree k and with at least (k+1)-point Gauss-Lobatto quadrature. In this talk, I will present some brand new results of this classical scheme, including its accuracy, monotonicity (stability), and examples of using monotonicity to construct high order bound-preserving schemes in various applications including the Allen-Cahn equation coupled with an incompressible velocity field, Keller-Segel equation for chemotaxis, and nonlinear eigenvalue problem for Gross–Pitaevskii equation. 1) Accuracy: when the least accurate (k+1)-point Gauss-Lobatto quadrature is used, the spectral element method is also a finite difference (FD) scheme, and this FD scheme can sometimes be (k+2)-th order accurate for k>=2. This has been observed in practice but never proven before in terms of rigorous error estimates. We are able to prove it for linear elliptic, wave, parabolic and Schrödinger equations for Dirichlet boundary conditions. For Neumann boundary conditions, (k+2)-th order can be proven if there is no mixed second order derivative. Otherwise, only (k+3/2)-th order can be proven and some order loss is indeed observed in numerical tests. The accuracy result also applies to spectral element method on any curvilinear mesh that can be smoothly mapped to a rectangular mesh, e.g., solving a wave equation on an annulus region with a curvilinear mesh generated by polar coordinates. 2) Monotonicity: consider solving the Poisson equation, then a scheme is called monotone if the inverse of the stiffness matrix is entrywise non-negative. It is well known that second order centered difference or P1 finite element method can form an M-matrix thus they are monotone, and high order accurate schemes in general are not M-matrices thus not monotone. But there are exceptions. In particular, we have proven that the fourth order accurate FD scheme (Q^2 spectral element method) is a product of two M-matrices thus monotone for a variable coefficient diffusion operator: this is the first time that a high order accurate scheme is proven monotone for a variable coefficient operator. We have also proven the fifth order accurate FD scheme (Q^3 spectral element method) is a product of three M-matrices thus monotone for the Poisson equation: this is the first time that a fifth order accurate discrete Laplacian is proven monotone in two dimensions (all previously known high order monotone discrete Laplacian in 2D are fourth order accurate).</div>Stechmannhttps://wiki.math.wisc.edu/index.php?title=Applied/ACMS&diff=22684Applied/ACMS2022-02-07T18:44:02Z<p>Stechmann: /* Spring 2022 */</p>

Title: Tensor Geometry in the Turbulent Cascade<br />
<br />
Abstract: Perhaps the defining characteristic of turbulent flows is the directed flux of energy from the scales at which it is injected into the flow to the scales at which it is dissipated. Often, we think about this transfer of energy in a Fourier sense; but in doing so, we obscure its mechanistic origins and lose any connection to the spatial structure of the flow field. Alternatively, quite a bit of work has been done to try to tie the cascade process to flow structures; but such approaches lead to results that seem to be at odds with observations. Here, I will discuss what we can learn from a different way of thinking about the cascade, this time as a purely mechanical process where some scales do work on others and thereby transfer energy. This interpretation highlights the fundamental importance of the geometric alignment between the turbulent stress tensor and the scale-local rate of strain tensor, since if they are misaligned with each other, no work can be done and no energy will be transferred. We find that (perhaps surprisingly) these two tensors are in general quite poorly aligned, making the cascade a highly inefficient process. Our analysis indicates that although some aspects of this tensor alignment are dynamical, the quadratic nature of Navier-Stokes nonlinearity and the embedding dimension provide significant constraints, with potential implications for turbulence modeling.<br />

Title: Recent extension of V.I. Arnold's and J.L. Synge's mathematical theory of shear flows<br />
<br />
Abstract:<br />
A viscous extension of Arnold’s non-viscous theory ([1]) for 2D wall-bounded shear flows is established ([3]). One special form of our linearized viscous theory recaps the linear perturbation’s enstrophy (vorticity) identity derived by Synge in 1938 ([2]). For the first time in literature, we rigorously deduced the validity of Synge’s identity under nonlinear dynamics and relaxed wall conditions. Furthermore, we discovered a new ‘weighted’ enstrophy identity.<br />
<br />
To illustrate the physical relevance of our identities, we quantitatively investigated mechanisms of linear instability/stability within the normal modal framework. We observed a subtle interaction between a critical layer and its adjacent boundary layer, which governs stability/instability of a flow. We also proposed a boundary control scheme that transitions wall settings from no-slip to free-slip, through which the 2D base flow was stabilized quickly at an early stage of the transition. Effectiveness of such boundary control scheme for 3D shear flows is yet to be tested by DNS/experiments.<br />
<br />
Apart from physics, I shall also talk about the potential of using our nonlinear enstrophy identity to generate rigorous bounds on flow stability.<br />

Title: Advances in Linear Inverse Modeling for Understanding Tropical Pacific Climate Variability<br />
<br />
Abstract:<br />
The El Nino / Southern Oscillation (ENSO) phenomenon in the tropical Pacific Ocean is the most energetic climatic phenomenon on Earth for interannual to decadal time scales, with substantial societal and environmental impacts around the world. Despite a well-developed theory for why ENSO events occur several aspects of ENSO variability are still poorly understood, including (1) why individual ENSO events tend to evolve with different spatial structures, (2) why ENSO events tend to be positively skewed (toward El Niño events rather than La Niña events), and (3) the role of deterministic dynamics vs. stochastic forcing in influencing ENSO growth and variance. In this talk, I will present recent work using a suite of Linear Inverse Models (LIMs) in which a linear dynamical operator (including state dependent noise, or cyclo-stationary dynamics) is derived from an existing set of observations. These LIMs can be used to (1) diagnose physical processes that cause growth toward a pre-defined spatial structure, (2) investigate how state-dependent (local) correlated additive and multiplicative noise (CAM-Noise) generates higher order moments (in a linear system forced by gaussian noise), and (3) the role of seasonality in generating ENSO variability and predictability. The talk will focus on development of the linear inverse model and on the application of the models in dynamical system analyses.</div>Stechmannhttps://wiki.math.wisc.edu/index.php?title=Applied/ACMS&diff=19650Applied/ACMS2020-09-04T13:24:21Z<p>Stechmann: /* Fall 2020 */</p>
