报告题目：Existence and stability of smooth traveling circular pairs for gSQG equation

报告摘要：The Lamb dipole is well-known for 2D Euler incompressible flow. In this talk, I will introduce some results of the existence and stability of travelling vortex pairs for the generalized surface quasi-geostrophic equation, which is the analogue of the Lamb dipole. This is based on a joint work with Guolin Qin, Weicheng Zhan and Changjun Zou.
