研究了四元数射影空间中的全实伪脐子流形的刚性,运用活动标架法和S.T.Yau广义极值原理,得到了关于第二基本形式模长平方、截面曲率的刚性定理,推广了已有理论的相关结果.
In this paper,the authors study totally real pseudo-umbilical submanifolds in a quaternion projective space.By using the moving-frame method and the Yau's maximum principle,some rigidity theorems on the sectional curvature and the squared length of the second fundamental form are obtained,which generalize some results in the relevant literatures.
