高余维中曲率流的Pinched古解

Pinched Ancient Solutions to the High Codimension Mean Curvature Flow

Stephen Lynch, Huy The Nguyen

摘要:

我们研究的解决方案,高余维中曲率流定义为所有的负时间,通常被称为古代的解决方案。证明了任何满足一定自然拼挤条件的第二基本型紧古解必是一族收缩球。Andrews和Baker证明了满足这个捏挤条件的初始子流形,它推广了凸性的概念,在流下收敛到圆点。作为一个应用,我们利用所得结果简化了它们的证明。

英文摘要:

We study solutions of high codimension mean curvature flow defined for all negative times, usually referred to as ancient solutions. We show that any compact ancient solution whose second fundamental form satisfies a certain natural pinching condition must be a family of shrinking spheres. Andrews and Baker have shown that initial submanifolds satisfying this pinching condition, which generalises the notion of convexity, converge to round points under the flow. As an application, we use our result to simplify their proof.
