摘要
主要讨论Ricci曲率具有正下界的紧Rieman流形M上的调和映射 .讨论了调和映射特征值的估计问题 ,得到了调和映射是全测映射的一个条件 .
A property of certain harmonic maps of Ricci curvature which have positive low bound on compact Riemann manifolds,as well as the Eigenvalue estimation problem of harmonic maps are discussed,we get a condition that a harmonic maps is a totally geodesic map.[WX(5KG0,40]
