Abstract: In this paper, a new approach to Banach contraction principle in fuzzy metric space is provided. The concepts of convergent sequence, Cauchy sequence, complete metric space, contractive map and existence of fixed points, are all defined with some degrees. Adopting these degree concepts, a degree representation of Banach contradiction principle in fuzzy metric space is given by means of an inequality.
Keywords: Fixed point theorem, fuzzy metric space, Banach contraction principle
