Abstract

Fuzzy metric spaces theory has an essential significance in mathematics, statistics, computer science, etc. In this paper, several basic properties of the fuzzy metric space (FM-space) ( ) are discussed. The concepts of fuzzy convergent sequence, fuzzy Cauchy sequence, fuzzy open ball and fuzzy closed ball are recalled, then main theorems related to these concepts are proved.
