Quasineutral Euler limit for the Vlasov-Poisson-Landau system

时   间：  2023-04-14 16:00 — 17:00

The formal limit of the one-dimensional Vlasov-Poisson-Landau (VPL) system in the combined small Knudsen and quasineutral regimes gives the compressible Euler system. In the talk I will present a recent result on the construction of global-in-time small-amplitude smooth solutions of the VPL system with an explicit rate of convergence to local Maxwellians whose fluid quantities are the Riemann rarefaction wave solutions to the limit Euler system. Joint with Dongcheng, Yang and Hongjun Yu.
