摘 要：In this talk, we investigate the global well-posedness in the critical spaces of 3D inhomogenous Navier-Stokes equations, which has variable kinematic viscosity under the smallness assumptions of initial velocity fields. Compared with the previous results，we remove the smallness assumption of \mu(\rho)-1 in L^{\infinity}. In addition, the decay estimate of the velocity fields is also obtained. It is a joint work with Lu Wang.
