Abstract

In this paper, we introduce a new class of fuzzy sets, namely, fuzzy ψ*-closed sets for
fuzzy topological spaces, and some of their properties have been proved. Further, we
introduce fuzzy ψ*-continuous, fuzzy ψ*-irresolute functions, and fuzzy ψ*-closed
(open) functions, as applications of these fuzzy sets, fuzzy T1/5-spaces, fuzzy T ψ1=5 -spaces, and fuzzy ψ*
T1/5-spaces.
