摘要
在FWC-空间上引入一类广义的T-KKM映象,建立了一些非空紧闭值映象的T-KKM型定理.利用此结果,获得了FWC-空间中的Fan-Browder不动点定理、Ky Fan截口定理和广义向量均衡问题解的存在性定理.
In this paper,we introduce a class of generalized T-KKM mapping in FWC-spaces and establish some T-KKM-type theorems of non-empty compact closed valued mappings.As application,Fan-Browder fixed point theorem,Ky Fan section theorem and existence theorem of solution for the generalized vector equilibrium problems are obtained in FWC-spaces.
