摘要
从Ricci曲率角度讨论了单位球面中具有常平均中曲率的紧教子流形,以及具有常数量曲率的紧致子流形,得到了两个Pinching定理.
In an unit sphere,the compact submanifold with constant mean curvature and the combact submanifold with constant scalar curvature are discussed frorn the angle of Ricci curvature. Two Pinching theorems are obtained,which extend some authors'corresponding results to a certain extent.
