Title: Landau damping and the long-time collisionless limit of the Vlasov-Poisson-Landau Equations

Speaker: Weiren Zhao

Abstract: In this talk, I will present recent joint work with Bedrossian and Zi on the long-time collisionless limit of the Vlasov-Poisson-Landau Equations (VPL). We establish the Landau damping for the solution to the VPL with initial data close to the global Maxwellian in Gevrey-(2-) class. Moreover, we proved that such a solution converges to the solution to the Vlasov-Poisson equation with the same initial data as the collision frequency approaches 0. 

Bio: Weiren Zhao earned his PhD from Zhejiang University, after that he moved to Peking University and NYU Abu Dhabi as a postdoctoral researcher. He is now an assistant professor at NYU Abu Dhabi. His research focuses on Functional analysis and the stability problems in PDEs.
