论文摘要
Bochner的经典定理断言，紧凑型riemannian歧管的等轴测组是有限的。在本文中，我们通过允许“小”阳性RICCI曲率提供了Bochner定理的几个扩展。
A classical theorem of Bochner asserts that the isometry group of a compact Riemannian manifold with negative Ricci curvature is finite. In this paper we give several extensions of Bochner's theorem by allowing "small" positive Ricci curvature.
