• 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
Keywords
Dislocated quasi metric, dq– limit, dq – convergent, dq – Cauchy sequence.
