This paper contains three chapters. we discuss the pinching problems on the length of the second fundamental form of compact space - like submanifolds mn with unit parallel mean curvature vector in the de sitter space spn + p. in particular, a sufficient condition for mn with constant scalar curvature to be totally umbilical is given
討論desitter空間s _ p ~ ( n + p )中具有平行的單位平均曲率向量的緊致類空子流形m ~ n的第二基本形式長度拼擠問題,給出了具有常數量曲率的這種子流形是全臍球面的一個充分條件。In the third second, we study a closed oriented submanifold with parallel mean curvature vector field in a sphere. let s = s - nh2. we fist obtain a pinching theorem on 5
第三節中研究了歐氏球面中具有常平均曲率向量子流形,獲得兩個結果,其中一個結果推廣了h
