题目：Nonlocal Power-type Curvature Flows of Immersed Locally Convex Curves
报告人：王小六 副教授 （东南大学）
Abstract: We provide sufficient conditions on an initial curve for the area preserving and the length preserving curvature flows of curves in the plane, to develop a singularity at some finite time or converge to an m-fold circle as time goes to infinity. For the area preserving flow, the positivity of the enclosed algebraic area determines whether the curvature blows up in a finite time or not, while for the length preserving curvature flow, it is the positivity of an energy associated with initial curve that plays such a rule.
