关于Schroeder和Strake的一个猜想

On a conjecture of Schroeder and Strake

Fengbo Hang, Xiaodong Wang

摘要:

我们证明了一些关于带边界的紧致流形的刚性结果。特别地,对于具有非负里奇曲率和单连通平均凸边界的紧致黎曼流形,证明了如果截面曲率在边界上为零,则度量必是平坦的.

英文摘要:

We prove some rigidity results for compact manifolds with boundary. In particular for a compact Riemannian manifold with nonnegative Ricci curvature and simply connected mean convex boundary, it is shown that if the sectional curvature vanishes on the boundary, then the metric must be flat.
