Abstract:In this talk, I will present  the global well-posedness of 3D inhomogenous Navier-Stokes  system with variable  viscosity only under the smallness assumptions of initial velocity fields in critical spaces.  Compared with the previous results, we remove the small conditions on the initial density by virtue of the velocity decomposition method. In addition, the decay rate of the velocity fields is necessary. It is a joint work with my Phd student Lu Wang.
