Abstract

Abstract: In this paper,we give a fixed point theorem for multi-valued composite increasing operators,which generalizes the theorem of the paper [1]under not only multi-valued mappings but also single-valued mappings.And we generalizes the corresponding results of [2]~[5].

Key words: , semiordered , topological , space, multi-valued , increasing , operator, upper-semiclosed set, fixed , , point
