摘 要:
In this talk, we give recent progress on diffusive limit of one-species Vlasov-Maxwell-Boltzmann system. By employing the weighted energy method with two newly introduced weight functions and some novel treatments, we solve this problem for the full range of cutoff hard potentials. Uniform estimate with respect to the Knudsen number is established globally in time, which eventually leads to the global existence of solutions to one-species Vlasov-Maxwell-Boltzmann system and hydrodynamic limit to the incompressible Navier-Stokes-Fourier-Maxwell system. This is a joint work with Weijun Wu, Weihua Gong and Yuan Xu.
