报告题目On global strong solutions to nonhomogeneous incompressible Navier-Stokes and MHD equations with vacuum

报告简介:

This talk concerned with the global well-posedness of strong solutions to the Cauchy problem of 2D NS and MHD equations with vacuum. First, it is proved that the 2D Cauchy problem of the nonhomogeneous incompressible NS equations admits a unique global strong solution provided that the initial density decays not too slow at infinity. Next, if both the initial density and the initial magnetic decay not too slow at infinity, we also establish the global existence and large time behavior of the strong solutions to the 2D nonhomogeneous incompressible MHD equations. In particular, the global strong solutions to both NS and MHD equations are not required any smallness assumptions on the initial data.
