局部对称黎曼流形的伪脐点子流形

Pseudo-Umbilal Submanifolds of Locally Symmetric Manifold

研究了局部对称黎曼流形的伪脐子流形, 得到了这种子流形的一个内蕴刚性定 理,从而推广了文献[3]中的结果。

The pseudo-Umbilical manifolds in a Locally symmetric Riemannian manifold are discussed, A intrinsic rigidity theorem is obtained, So the correspond result due to [3]is generalized.
