报告摘要:In this talk, I will present our results on some approximation radiation hydrodynamic systems, including the pointwise estimate of the solution of the radiation hydrodynamic equations in 1-D, the asymptotic stability of the rarefaction wave of equilibrium approximation equation in 1-D,  the existence and time decay rate of the solutions of the P1 radiation hydrodynamic system in 3D with viscosity. These models arise from the radiation hydrodynamics which describes the macroscopic fluid motion and a $P_1$ approximation of the transport equation. (Jointed works with S.J. Deng, K.Q. Li, F. Xie and W.J. Wang).
