On the forms of continuity for fuzzy functions

... Proof. Let µ be any fuzzy open set in Y . Since Y is fuzzy PΣ , there exists a family Ψ whose members are fuzzy regular closed set of Y such that µ = ∨{ρ : ρ ∈ Ψ}. Since f is fuzzy almost contra-β-continuous, f −1 (ρ) is fuzzy β-open in X for each ρ ∈ Ψ and f −1 (µ) is fuzzy β-open in X. Therefore, ...

... present paper, we introduce and characterize the notion of fuzzy L-Hausdorff spaces which is a generlization of some fuzzy concepts by using a fuzzy L-open sets , we also define the class of fuzzy irresolute functions via fuzzy topological ideals and investigate its relation to fuzzy L-Hausdorff spa ...

Some types of fuzzy open sets in fuzzy topological groups

A fuzzy set in (X,τ) is said to be quasi-coincident with a fuzzy set B, denoted by AqB, if there exists x∈X such that A(x) + B(x) >1 [16]. A fuzzy set V in (X,τ) is called a q-ne ...
