講演: Time Asymptotical Behavior of  Vlasov-Poisson-Boltzmann Equation
Prof. Hailiang Li
(Department of Mathematics, Capital Normal University, China)
要旨: We present the recent analysis of the spectrum and long time decay rates of  Vlasov-Poisson-Boltzmann Equation, and justify the influence of electric field on the distribution of spectrum of linearized  Vlasov-Poisson-Boltzmann Equation near a global Maxwellian. It is joint work with T. Yang and M.-Y. Zhong.

講演: Regularity and singularity of Boltzmann equation with boundary
Dr. Chanwoo Kim
(DPMMS, Centre for Mathematical Sciences, Cambridge University, UK)
要旨: We discuss the singular behavior of Boltzmann solution near the boundary. When the domain is convex we introduce the weight function to control the singularity near the boundary. With this weight function we are able to estimate the first derivatives of Boltzmann solution. We show that, however, second derivatives may not exist up to the boundary.
