Title: Landau damping in plasma physics
Abstract: After a quick overview on the classical notion of Landau damping discovered by Landau in 1946, the colloquium will highlight recent mathematical advances on understanding the damping and the large time behavior of a plasma modeled by Vlasov-Poisson and Vlasov-Poisson-Landau systems, including (1) an elementary proof of nonlinear Landau damping for analytic and Gevrey data (joint work with E. Grenier from ENS Lyon and I. Rodnianski from Princeton) and (2) nonlinear Landau damping in the weakly collisional regime for a threshold of initial data with Sobolev regularity (joint work with S. Chaturvedi and J. Luk from Stanford).
