Abstract:

We investigate various classes of generalized closed fuzzy sets in -topological spaces, namely, -closed fuzzy sets and -closed fuzzy sets. Also, we introduce a new separation axiom of the -topological spaces, and we prove that every -space is a -space. Furthermore, we using the new generalized closed fuzzy sets to construct new types of fuzzy mappings.
