| Mathematical results arising from systems biology |
|
We describe new sufficient conditions for global injectivity of general nonlinear functions, necessary and sufficient conditions for global injectivity of polynomial functions, and related criteria for uniqueness of equilibria in nonlinear dynamical systems. Some of these criteria are graph-theoretical, others are checked using symbolic computation. We also mention some applications of these methods in the study of Bezier curves and patches, and other types of manifolds used in geometric modeling. Also, we discuss some criteria for persistence and boundedness of trajectories in polynomial or power-law dynamical systems. All these seemingly unrelated results have been inspired by the study of mathematical models in systems biology. |

| Fluid-particle flows |
|
We are interested in flows where a disperse phase (particles) is coupled to a dense phase (fluid). The evolution of the mixture is described by a kinetic equation coupled to a hydrodynamic system (Euler or Navier-Stokes). We will discuss several mathematical questions, with a particular attention paid to asymptotic issues. We will also present relevant numerical schemes specifically adapted to the asymptotic regime. |
