2—距离空间中集值映射的公共不动点定理

Common Fixed Point Theorems for Set—Valued Mappings in 2—Metric Spaces

本文研究2-距离空间中一类集值映射的不动点的存在性条件,所得结果是单值情况的推广和发展。

In this paper,we study the existence conditions of common fixed points for a class of Set—Valued mappings in a 2—metric Space.The results presented in this paper are the generalization of the corresponding results of the single—valued nonexpansive map- pings.
