摘要：

A uniformly continuous mapping with a certain modulus of continuity between two metric spaces was studied. The hyperconvexity of one of the metric spaces was defined and results related to the ball intersection properties, extension of linear operators and extension of uniformly continuous mappings were listed. A fixed point theorem on hyperconvex metric spaces was also proved.
