摘要
利用Riemann曲率与Weyl共形曲率研究了特殊的Riemann流形———伪Ricci对称流形.同时得到了流形与子流形成为Ricci平坦空间的充要条件.
Specific Riemann manifolds-pseudo Ricci symmetric manifolds are studied by using Riemann curvature and Weyl conformal curvature, and necessary and sufficient conditions of manifolds and submannifolds become Ricci-flat space are given.
