Venue：Room 224，Nanhai Building

Topic：On Well-Posedness of Incompressible MHD

Abstract: In this talk, we will first review recent results on the well-posedness of 2D incompressible MHD equations with partial viscosity and fractional diffusions. Then we will focus on a kind of 3D axisymmetric solutions to 3D incompressible MHD equations with only vertical viscosity.

Speaker: Professor Jiu Quan-sen, Capital Normal University
