摘要：The paper contains a study of fuzzy θ-closure operator, θ-closures of fuzzy sets in a
fuzzy topological space are characterized and some of their properties along with their relation with
fuzzy δ-closures are investigated. As applications of these concepts, certain functions as well as
some spaces satisfying certain fuzzy separation axioms are characterized in terms of fuzzy θ-closures
and δ-closures.
