Abstract
The main purpose of this article is to introduce and study a concept of a generalized type of fuzzy closed (open) sets in a fuzzy topological space that is endowed with a fuzzy stack. Also several properties of these sets have been studied. Finally by using the aforesaid kind of generalized fuzzy closed sets, we have defined and studied two classes of functions between such spaces, which turn out to be respectively smaller and larger than that of fuzzy continuous functions.
