本文研究了具有非负Ricci曲率和内射半径自下有界的完备开流形。我们发现当某些距离函数满足一个合理的条件时,这类流形是欧氏空间的微分同胚。
In this paper, we study complete open manifolds with nonnegative Ricci curvature and injectivity radius bounded from below. We find that this kind of manifolds are diffeomorphic to a Euclidean space when certain distance functions satisfy a reasonable condition.
