内容摘要: In the talk, we are concerned with the compressible Euler limit of the Landau equation for Coulomb potentials in the whole space. We develop a method of high-order energy estimates involving the small Knudsen number. Applications to other physical situations where the self-consistent electromagnetic field is coupled will also be discussed. In particular, we also establish the convergence of smooth solutions of the Vlasov-Maxwell-Boltzmann/Landau system to the ones of the Euler-Maxwell system in the compressible setting. These are joint works with Dongcheng Yang and Hongjun Yu.
