Speaker:Yuchen Wang

Abstract:

In this talk, we will consider the existence and uniqueness of steady concentrated vorticities of the 2-D incompressible Euler equation on smooth bounded domains and study their stability. Given steady non- degenerate point vortices configurations, we construct such steady piece- wisely constant vortex flows and study their linear stability. Steady con- centrated Lipschitz continuous vorticities are also been considered. Both of them are highly concentrated near the given steady vortex points. This talk is mainly based on a joint work with Prof. Yiming Long and Prof. Chongchun Zeng.
