正曲率流形的第一特征值

The first eigenvalue on a compact manifold with positive Ricci curvature

主要讨论具有正Ricci曲率的紧Riemann流形上的第一特征值 ,给出一种下界估计 .

In this paper,we mainly discuss the first eigenvalue on a compact Riemannia manifold with positive Ricci curvature.A kind of lower bound for the eigenvalue is obtained.
