Sasakian空间型中的极小积分子流形

The Minimal Integal Submanifolds in a Sasakian Space Form

设Ｍ￣ｎ是２ｎ＋１维Ｓａｓａｋｉａｎ空间型Ｍ￣（２ｎ＋１）（Ｃ）中ｎ维极小的积分子流形．本文给出了Ｍ￣ｎ为全测地的一些Ｐｉｎｃｈｉｎｇ条件．

Let M￣n be an n-dimensitinal minimal integral submanifold in a(2n+1)-dimensional sasakian space form M￣(2n+1)(C).In this paper,some pinchingconditions which M￣n is totally geodesic submanifold are given.
