报告摘要：In this talk, we are concerned with the large-time behavior of planar stationary solution to the compressible heat conducting gas under outflow or inflow condition in R^3_+. (1) It is shown that a corresponding planar stationary solution to outflow problem is time-asymptotically stable, provided the initial perturbation in a certain Sobolev space and the boundary strength are sufficiently small. (2) Moreover, the convergence rate of the solution toward the stationary solution is obtained, provided that the initial perturbation belongs to the weighted Sobolev space. Each proof is given by deriving a-priori estimates of the perturbation from the stationary wave by using a time and space weighted energy method.
