摘要:

利用活动标架法和广义极值原理研究四元数射影空间中的全实2-调和子流形, 得到了这类子流形在伪脐条件下是极小的, 并给出关于第二基本形式模长平方的刚性定理和完备全实2调和子流形是极小的充分条件.

Abstract:

The authors studied totally real biharmonic submanifolds in a quaternion projective space by the movingframe method under the guidance of  maximum principle, proved the minimum of pseudoumbilical biharmonic submanifolds and the rigidity theorem on the square of the lenghth of the second fundamental form. And we also gave several sufficient conditions under which complete totally real biharmonic submanifolds are minimal.

Key words: quaternion projective space, biharmonic, minimal submanifold
