摘要:In this talk, we present some of our work on the qualitative analysis of nonlinear PDEs’.The main topics are no the study of regularity, a priori estimates, and Liouville type theorems. We give a brief introduction on the problems, the related methods, and some results with applications.
Our presentation is focused on problems arising from the study of the incompressible Navier-Stokes and Euler equations.Most of the results presented here are the joint work with Chenkai Liu, Yingshu Lv, Chunjing Xie, Shaodogn Wang and Ran Zhuo.
