報(bào)告摘要:
In this talk, we gives some recently results on the 3D micropolar fluids system, such as the existence of global weak solution for incompressible micropolar fluids equations with bounded density. 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). Moreover, we also discuss the global existence and optimal decay of the solution for the 3D compressible micropolar system with a class of the large initial data. This work is joint with T. Zhang.
