简介 Description

Title: The convergence and rigidity of mean curvature flow in arbitrary codimension 

Speaker: Prof.  Entao Zhao (Zhejiang University) 

Tencent Meeting ID:  168 504 661 

Time: 2021-11-06, 14:00-15:00 

Abstract: In this talk, I will first review the rigidity and sphere theorems for submanifolds, which are motivations of our research on mean curvature flow.

Then I will discuss some convergence results for mean curvature flow of arbitrary codimension. At last, I will talk about our recent results

on the rigidity of ancient mean curvature flow under curvature pinching conditions.

This talk is based on the joint works with Prof. Kefeng Liu, Prof. Hongwei Xu and Dr. Li Lei.

Title:Poincare inequality on area-minimizing hypersurfaces 

Speaker:  Prof. Qi Ding (Fudan University) 

Tencent Meeting ID:   168 504 661 

Time:  2021-11-06, 15:30-16:30 

Abstract: In this talk, I will talk about Neumann-Poincare inequality on area-minimizing hypersurfaces in

Euclidean space and manifolds of almost nonnegative Ricci curvature.
