• A COMMON FIXED POINT THEOREM FOR FOUR SELF MAPS IN COMPLEX VALUED AND VECTOR VALUED METRIC SPACES

Abstract

In this paper we prove a common fixed point theorem for four self maps f, g, S and T in complex valued metric spaces where both {f, S} and {g, T} are weakly compatible self maps of a nonempty set X. Our result generalizes the results of Sandeep Bhatt et al [2]. We also introduce the concept of a vector valued metric space as a generalization of complex valued metric space and prove some fixed point theorems in these spaces.
