球面上具有自由边界的非负曲超曲面

Nonnegatively curved hypersurfaces with free boundary on a sphere

Mohammad Ghomi, Changwei Xiong

摘要:

本文证明了在欧几里得空间$R^{n+1}$中,球面$S^n$上任何具有自由边界的紧致浸入非负曲率超曲面$M$是嵌入凸拓扑圆盘.特别地,当$M$的$m^{th}$中曲率恒定时,对于任何$1\leq m\leq n$,$M$是球冠或赤道盘。

英文摘要:

We prove that in Euclidean space $R^{n+1}$ any compact immersed nonnegatively curved hypersurface $M$ with free boundary on the sphere $S^n$ is an embedded convex topological disk. In particular, when the $m^{th}$ mean curvature of $M$ is constant, for any $1\leq m\leq n$, $M$ is a spherical cap or an equatorial disk.
