The Continuity of Fuzzy Metric Spaces
Abstract
In the present paper, the definitions of a fuzzy continuous function and uniformly fuzzy continuous are introduced. we prove that a function from a fuzzy metric space ( ) into a fuzzy metric space ( ) is fuzzy continuous if and only if for every fuzzy open subset of , is fuzzy open in . Also the composition function of two uniformly fuzzy continuous functions is proved to be a uniformly fuzzy continuous function.
