摘要 文章讨论了Sasakian空间形式中标准平均曲率向量平行的C-全实伪脐子流形,得到了紧致的C-全实伪脐子流形的一个刚性结果. In this paper we discuss the C - totally real pseudo - umbilical submanifolds with parallel unit mean curvature vector of a Sasakian space form. We obtain a rigidity result for the compact C - totally real pseudo - umbilical submanifolds.
