有关球面凸集的几个Helly型定理
Several theorems of Helly type for spherically convex sets
摘要
Abstract
In this paper,we introduced a kind of spherical translations and established some theorems of Helly type for spherically convex sets concerned with these spherical translations. The conclusions obtained here are analogues of those for convex sets in spherical spaces. This contributes to the further study on spherical convexity.关键词
