1. Introduction
There have been a number of generalizations of metric space. One such generalization is Menger space initiated by Menger [6]. It is a probabilistic generalization in which we assign to any two pointsxandy, a distribution functionFx,y. Schweizer and Sklar [9] studied this concept and gave some fundamental results on this space. It is observed by many authors that contraction condition in metric space may be exactly translated into PMspace endowed with min norms. Sehgal and BharuchaReid [10] obtained a general ization of Banach Contraction Principle on a complete Menger space which is a milestone in developing fixedpoint theorems in Menger space.
