摘要：
In this paper, we prove the global well-posedness of 3D inhomogeneous incompressible Navier-Stokes equations with initial velocity to be sufficiently small in the critical Besov space,.over dot(B)(p,1)(3/p-1) for 1 < p < 6 and with initial density in the critical Besov space and bounded away from vacuum. The key ingredient used in the proof lies in a new estimate to the pressure term. In particular, our result improves the previous ones by Abidi et al. (2013) [3], Zhai and Yin (2017) [32], Burtea (2017) [6] and so on.
