局部对称共形平坦黎曼流形中的子流形

THE SUBMANIFOLDS IN A LOCALLY SYMMETRIC AND CONFORMALLY FLAT RIEMANNIAN MANIFOLD

讨论了局部对称共形平坦黎曼流形中具有平行单位平均曲率向量的子流形 ,改进了孙华飞(1992 )

The submanifolds with parallel unit mean curvature vector in a locally symmetric and conformally flat Riemannian manifold are discussed and the result in Sun Hua_fei' paper in 1992 is improved.
