''Counting embedded curves in Calabi-Yau threefolds and Gopakumar-Vafa invariants''<br />
<br />
Gopakumar-Vafa BPS invariant is some integer counting invariant of the cohomology<br />
of D-brane moduli spaces in string theory. In relation to the Gromov-Witten theory,<br />
it is expected that the invariant would coincide with the `number' of embedded<br />
(pseudo)holomorphic curves (Gopakumar-Vafa conjecture). In this talk, we will explain the speaker's recent<br />
result that the latter integer invariants can be defined for a generic choice of<br />
compatible almost complex structures. We will also discuss the corresponding<br />
wall-crossing phenomena and some open questions towards a complete solution to<br />
the Gopakumar-Vafa conjecture.<br />
<br />
===Leva Buhovsky (U of Chicago)===<br />
''On the uniqueness of Hofer's geometry''<br />
<br />
In this talk we address the question whether Hofer's metric is unique among the Finsler-type bi-invariant metrics on the group of Hamiltonian diffeomorphisms. The talk is based on a recent joint work with Yaron Ostrover.<br />
<br />
===Leonid Polterovich (Tel Aviv U and U of Chicago)===<br />
''Poisson brackets and symplectic invariants''<br />
<br />
We discuss new invariants associated to collections of closed subsets <br />
of a symplectic manifold. These invariants are defined <br />
through an elementary variational problem involving Poisson brackets.<br />
The proof of non-triviality of these invariants requires methods of modern<br />
symplectic topology (Floer theory). We present applications<br />
to approximation theory on symplectic manifolds and to Hamiltonian dynamics.<br />
The talk is based on a work in progress with Lev Buhovsky and Michael Entov.<br />
<br />
===Sean Paul (UW Madison)===<br />
''Canonical Kahler metrics and the stability of projective varieties"<br />
<br />
I will give a survey of my own work on this problem, the basic reference is:<br />

===Markus Banagl (U. Heidelberg)===<br />
''Intersection Space Methods and Their Application to Equivariant Cohomology, String Theory, and Mirror Symmetry.''<br />
<br />
Using homotopy theoretic methods, we shall associate to certain classes of<br />
singular spaces generalized geometric Poincaré complexes called intersection<br />
spaces. Their cohomology is generally not isomorphic to intersection<br />
cohomology.<br />
In this talk, we shall concentrate on the applications of the new<br />
cohomology theory to the equivariant real cohomology of isometric actions of<br />
torsionfree discrete groups, to type II string theory and D-branes, and to<br />
the relation of the new theory to classical intersection cohomology under<br />
mirror symmetry.<br />
<br />
===Ke Zhu (U of Minnesota)===<br />
''Thick-thin decomposition of Floer trajectories and adiabatic gluing''<br />
<br />
Let f be a generic Morse function on a symplectic manifold M. <br />
For Floer trajectories of Hamiltonian \e f, as \e goes to 0 Oh proved that <br />
they converge to “pearl complex” consisiting of J-holomorphic spheres <br />
and joining gradient segments of f. The J-holomorphic spheres come from the <br />
“thick” part of Floer trajectories and the gradient segments come from <br />
the “thin” part. Similar “thick-thin” compactification result has <br />
also been obtained by Mundet-Tian in twisted holomorphic map setting. In <br />
this talk, we prove the reverse gluing result in the simplest setting: we <br />
glue from disk-flow-dsik configurations to nearby Floer trajectories of <br />
Hamitonians K_{\e} for sufficiently small \e and also show the <br />
surjectivity. (Most part of the Hamiltonian K_{\e} is \ef). We will discuss <br />
the application to PSS isomorphism. This is a joint work with Yong-Geun Oh.<br />
<br />
===Sergei Tabachnikov (Penn State)===<br />
''Algebra, geometry, and dynamics of the pentagram map''<br />
<br />
Introduced by R. Schwartz almost 20 years ago, the pentagram map acts on plane n-gons, considered up to projective equivalence, by drawing the diagonals that connect second-nearest vertices and taking the new n-gon formed by their intersections. I shall survey recent work on the pentagram map, in particular, I shall demonstrate that the dynamics of the pentagram map is completely integrable. I shall also explain that the pentagram map is a discretization of the Boussinesq equation, a well known completely integrable partial differential equation. A surprising relation between the spaces of polygons and combinatorial objects called the 2-frieze patterns (generalizing the frieze patterns of Coxeter) will be described. Eight new(?) configuration theorems of projective geometry will be demonstrated. The talk is illustrated by computer animation.<br />
<br />
===Ma Chit (Chinese U. of Hong Kong)===<br />
''A growth estimate of lattice points in Gorenstein cones using toric Einstein metrics''<br />
<br />
Using the existence of Einstein metrics on toric Kahler and Sasaki manifolds, a lower bound estimate on the growth of lattice points is obtained for Gorenstein cones. This talk is based on a joint work with Conan Leung. <br />
<br />
===Eric Zaslow (Northwestern University)===<br />
''Ribbon Graphs and Mirror Symmetry''<br />
<br />
I will define, for each ribbon graph, a dg category,<br />
and explain the conjectural relation to mirror symmetry.<br />
I will being by reviewing how T-duality relates<br />
coherent sheaves on toric varieties to constructible sheaves<br />
on a vector space, then use this relation to glue<br />
toric varieties together. In one-dimension, the<br />
category of sheaves on such gluings has a<br />
description in terms of ribbon graphs.<br />
These categories are conjecturally<br />
related to the Fukaya category of a noncompact<br />
hypersurface mirror to the variety with toric<br />
components.<br />
<br />
I will use very basic examples.<br />
This work is joint with Nicolo' Sibilla<br />
and David Treumann.<br />

===Wenxuan Lu (MIT)===<br />
''Instanton Correction, Wall Crossing And Mirror Symmetry Of Hitchin's Moduli<br />
Spaces''<br />
<br />
We study two instanton correction problems of Hitchin's moduli spaces along with<br />
their wall crossing formulas. The hyperkahler metric of a Hitchin's moduli space<br />
can be put into an instanton-corrected form according to physicists Gaiotto,<br />
Moore and Neitzke. The problem boils down to the construction of a set of<br />
special coordinates which can be constructed as Fock-Goncharov coordinates<br />
associated with foliations of quadratic differentials on a Riemann surface. A<br />
wall crossing formula of Kontsevich and Soibelman arises both as a crucial<br />
consistency condition and an effective computational tool. On the other hand<br />
Gross and Siebert have succeeded in determining instanton corrections of<br />
complex structures of Calabi-Yau varieties in the context of mirror symmetry<br />
from a singular affine structure with additional data. We will show that the<br />
two instanton correction problems are equivalent in an appropriate sense. This<br />
is a nontrivial statement of mirror symmetry of Hitchin's moduli spaces which<br />
till now has been mostly studied in the framework of geometric Langlands<br />
duality. This result provides examples of Calabi-Yau varieties where the<br />
instanton correction (in the sense of mirror symmetry) of metrics and complex<br />
structures can be determined.<br />

''A plethora of exotic Stein manifolds''<br />
<br />
In real dimensions greater than 4, I will explain how a smooth <br />
manifold underlying an affine variety admits uncountably many distinct<br />
(Wein)stein structures, of which countably many have finite type,<br />
and which are distinguished by their symplectic cohomology groups.<br />
Starting with a Lefschetz fibration on such a variety, I shall per-<br />
form an explicit sequence of appropriate surgeries, keeping track of<br />
the changes to the Fukaya category and hence, by understanding<br />
open-closed maps, obtain descriptions of symplectic cohomology af-<br />
ter surgery. (joint work with P. Seidel)<br />
