论文摘要
在本说明中，我们证明，对于完整的非2级三维riemannian歧管，具有有界截面曲率的歧管，如果它具有均匀的正标曲率，则在注射率半径上有一个均匀的下限。
In this note, we prove that for a complete noncompact three dimensional Riemannian manifold with bounded sectional curvature, if it has uniformly positive scalar curvature, then there is a uniform lower bound on the injectivity radius.
