报告题目：Hilbert Expansion for the Relativistic Vlasov-Maxwell-Landau System  

报告摘要：The two-species relativistic Vlasov-Maxwell-Landau system is the most fundamental and complete model describing the dynamics of a dilute plasma, in which particles interact through Coulombic collisions and through their self-consistent electromagnetic field. A rigorous derivation from the two-species relativistic Vlasov-Maxwell-Landau system to the two-fluid relativistic Euler-Maxwell system  is a longstanding major open problem in the kinetic theory. We establish the global-in-time validity of Hilbert expansion for the relativistic Vlasov-Maxwell-Landau system and derive the limiting two-fluid relativistic Euler-Maxwell system as the Knudsen number goes to zero.  Our proof is based on a new time-dependent energy method, which is inspired by the pioneer work of Caflisch in 1980.
