报告摘要： We talk about the 3D inhomogeneous Micropolar Fluidsfluids system in critical space. We obtain the global well-posedness for the system with density-dependent viscosity in case the initial density and velocity in the critical Besov spaces. Moreover, we also discuss the existence of global weak solution for incompressible Micropolar Fluids equations with the initial density is only bounded. This result corresponds to the celebrated Leray estimate on lifespan of strong solutions to the classical Navier-Stokes equations and the interesting results for 3D inhomogeneous incompressible Navier-Stokes equations by P.Zhang (Adv. Math.2020). This work is joint with Y.Qu，，，H. Chen and T. Zhang.
