• A COINCIDENCE POINT THEOREM FOR FOUR SELF MAPPINGS IN DISLOCATED QUASI METRIC SPACES

Abstract

In this paper we prove a coincidence point theorem in dislocated metric spaces, provide a supporting example and extend the theorem to dislocated quasi metric spaces. We observe that the supporting example  of  a  result  of  K.P.R. Rao  and  P. Ranga Swamy ([7]) , on the existence of  a coincidence point for four self maps on a dislocated metric space is not valid . We also make a modification of their result
