Some rigidity theorems for self-shrinkers of the mean curvature flow

Hezi Lin

Abstract

In this paper, we first prove some Liouville type theorems for elliptic inequalities on weighted manifolds which support a weighted Sobolev-type inequality. Secondly, applying the Liouville type theorems to self-shrinkers, we obtain some global rigidity theorems.

Keywords: self-shrinkers, global rigidity, weighted manifolds

MSC numbers: Primary 53C44, 53C21
