报告内容简介：

In this talk, we discuss stability and instability of Kelvin-Stuart vortices. We prove that the whole family of Kelvin-Stuart vortices is nonlinearly stable for co-periodic perturbations, and linearly unstable for multi-periodic or modulational perturbations. If time is permitted, we discuss stability and instability of Kelvin-Stuart magnetic islands, which are magnetostatic equilibria for the 2D ideal MHD equations. This talk is based on a joint work with Dr. Shasha Liao and Prof. Zhiwu Lin.
