报告摘要:I will discuss the topic of linear and nonlinear stability of homogeneous equilibria among solutions of the Vlasov-Poisson system, both in the unconfined Euclidean space and in the confined periodic domains. The Euclidean problem differs significantly from the classical work on Landau damping in the periodic setting, in several ways. Most importantly, the linearized problem cannot satisfy a “Penrose condition”. As a result, our system contains resonances (small divisors) and the electric field can decay at most polynomially. This is joint work with Benoit Pausader, Xuecheng Wang, and Klaus Widmayer.
