局部CAT(k)空间上的一个Toponogov型比较定理
A Toponogov-type comparison theorem for locally CAT(k)spaces
摘要
Abstract
This paper studies the Toponogov-type properties of locally Cartan-Alexandrov-Toponogov(CAT(k))spaces.Based on the globalization theorem for Alexandrov spaces with a lower curvature bound,a Toponogov-type comparison theorem for locally CAT(k)spaces is presented,which proves the globalization theorem for locally CAT(k)spaces.关键词
