报告内容:

In this talk, we will report some recent results on the large-time behavior of solutions to the initial and initial boundary value problems with large initial data for the compressible Navier-Stokes system describing the one-dimensional motion of aviscous heat-conducting perfect polytropic gas in unbounded domains.The temperature is proved to be bounded from below and above independently of both time and space. Moreover, it is shown that the global solution is  asymptotically stable as time tends to infinity. Note that the initial data can be arbitrarily large.This result is proved by using elementary energy methods.\
