报告题目:On Two-Dimensional Compressible Magnetohydrodynamic Equations with Vacuum
报告摘要:In this talk, we consider the Cauchy problem of partial differential equations forviscous barotropic compressible magnetohydrodynamic flows in two or three spatial dimensions with vacuum as far field density. For two spatial dimensions, when the smooth initial data are of small total energy, we establish the global existence and uniqueness of strong solutions (which may be of possibly large oscillations). The key tool is some new a priori decay rates (in large time) for the pressure and the spatial gradients of both the velocity field and the magnetic field. Moreover, for three spatial dimensions case, some decay rates (in large time) are also obtained for the global strong solutions.
