球面凸函数的性质与判别法
Properties and criterions of spherically convex functions
摘要
Abstract
In this paper,we studiedthe properties and criterions of spherically convex functions. The continuity of spheri-cally convex functions was confirmed,and two criterions were established,which are the spherical analogues of those for convex functions. The results obtained here enrich the theory on spherically convex functions and contribute to the further study.关键词
