EDP : Josephine Evans (Univ. Paris Dauphine) : Quantitative rates of convergence to equilibrium for kinetic equations with spatially inhomogeneous jump rates.
Bâtiment Sophie Germain, salle G204I will discuss kinetic equations whose jump rate $sigma(x)$ depends on the position in space. Exponential convergence to equilibrium for such equations was proved to be equivalent to a geometric control condition by Bernard and Salvarani for the zero potential
