活动内容摘要:
Here, we focus on maximum principles, Liouville type theorems, classi cation of solutions and give a brief introduction of some problems and results on qualitative study of some nonlinear elliptic type PDEs.
We start with some recent work on the incompressible Navier- Stokes and Euler equations and give a short introduction of some re- lated methods, and some results with applications. Then, we focus on the Hardy-Littlewood-Sobolev system and curvatures related geomet- ric equations as examples to illustrate the ideas, methods and possible applications.
