流形的拓扑和曲率有着密切的联系,本文中,讨论了具有部分非负Ricci曲率的流形的拓扑并得到了其基本群增长的估计.
流形的拓撲和麯率有著密切的聯繫,本文中,討論瞭具有部分非負Ricci麯率的流形的拓撲併得到瞭其基本群增長的估計.

As well known, the topology and the curvature on a manifold have a very close relationship. In the paper stated here, the topology of a manifold with partially nonnegative Ricci curvature is considered and the estimate of the growth of its fundamental group is obtained.
