报告摘要:In this talk, we study the pointwise space-time behaviors of the Green's function and the global solution to the Vlasov-Poisson- Fokker-Planck (VPFP) system in three dimensional space. It is shown that the Green's function consists of the diffusion waves decaying exponentially in time but algebraically in space, and the singular kinetic waves which become smooth for all (t,x,v) when t>0. Furthermore, we establish the pointwise space-time behaviors of the global solution to the nonlinear VPFP system when the initial data is not necessarily smooth in terms of the Green's function.
