凸性是$CAT(κ)$空间中的一个局部性质
Convexity is a local property in $CAT(κ)$ spaces
摘要:
本文证明了$CAT(κ)$空间的连通闭局部凸子集(如果$κ>0$的话,则关于诱导长度度量的直径有一个额外的假设)是凸的.
英文摘要:
In this note we show that a connected, closed and locally convex subset (with an extra assumption on the diameter with respect to the induced length metric if $κ>0$) of a $CAT(κ)$ space is convex.
