P－Sasakian流形的斜半不变子流形

SKEW SEMI INVARIANT SUBMANIFOLDS OF A P SASAKIAN MANIFOLD

定义并讨论了Ｐ－Ｓａｓａｋｉａｎ流形的子流形为斜半不变子流形的一个充分条件。

In this paper we introduce and study the skew semi invariant submanifolds of a P Sasakian manifold, we obtain a sufficient condition for a submani fold of a P Sasakian mani fold to be a skew semi invariant submanifold. Also, we get a series important results about the curvature of this class of submani folds.
