题目: Universality in mean curvature flow neckpinches
 
Abstract: 
It is well known certain surfaces driven by its mean curvature vector will collapse in finite time. For a surface of revolution, almost everything has been understood: the surface will asymptotically become a cylinder around the collapsing time. For non-revolution surfaces, the results had to proved under the assumption that the collapsing cylinder is unique.
The proof of the uniqueness of the cylinder was open, despite numerous attempts had been made. In this talk we will present our recent results, which proved the uniqueness for a generic class of initial surface.
