报告内容简介：

In this talk, I will report three recent results on compressible MHD system with large initial data. Firstly, we consider a special 2D non-isentropic compressible viscous non-resistive MHD system, existence of global weak solutions is proved with finite energy initial data. Secondly, we consider the general 3D isentropic compressible MHD system with any adiabatic exponent greater than 1, we introduce the concept of dissipative weak solutions and prove the weak-strong uniqueness principle. In particular, we prove the existence by constructing suitable numerical solutions. Thirdly, we consider a special 2D compressible viscous non-resistive MHD system with general inflow-outflow boundary conditions, existence of global weak solutions is proved with finite energy initial data. Weak-strong uniqueness property is also established.
