关于半球的一个刚性定理

A Rigidity Theorem for the Hemisphere

Fengbo Hang, Xiaodong Wang

摘要:

证明了如下刚性定理:对于一个n维紧致黎曼流形,若其边界的里奇曲率下有界于n-1,则它的边界等距于n-1维标准球面且全测地,则该流形等距于标准半球.

英文摘要:

We prove the following rigidity theorem: For an n-dimensional compact Riemannian manifold with boundary whose Ricci curvature is bounded by n-1 from below, if its boundary is isometric to the standard sphere of dimension n-1 and totally geodesic, then the manifold is isometric to the standard hemisphere.
