We study operations on fuzzy languages such as union, concatenation, Kleene ⋆, intersection with regular fuzzy languages, and several kinds of (iterated) fuzzy substitution. Then we consider families of fuzzy languages, closed under a fixed collection of these operations, which results in the concept of full Abstract Family of Fuzzy Languages or full AFFL. This algebraic structure is the fuzzy ...

We present some properties regarding Darboux property, non-atomicity, regular fuzziness of multimeasures taking values in the family of all closed nonvoid subsets of a real normed space. Key–words: Darboux property, fuzzy multimeasure, atom, non-atomic, regular, diffused.

In this paper, we introduced the concepts of g ** -closed sets as well as g ** -open sets and studied some of their basic properties. Further we defined g ** -continuous mappings and investigated their basic properties. In addition we obtained g ** -irresolute mappings and some of their properties are derived.

In this paper we introduce intuitionistic fuzzy completely regular weakly generalized continuous mappings and some of their properties are studied.

In this paper we investigate common xed point theorems for contraction mapping in fuzzy metric space introduced by Gregori and Sapena [V. Gregori, A. Sapena, On xed-point the- orems in fuzzy metric spaces, Fuzzy Sets and Systems, 125 (2002), 245-252].

in this paper, we introduce and characterize fuzzy wea-kly $e$-closed functions in fuzzy topological spaces and the relationship between these mappings and some properties of them are investigated.
