On generalized fuzzy bitopological spaces

Boletim da Sociedade Paranaense de Matemática
This paper is devoted to introduce the new classes namely generalized fuzzy bitopological spaces and defined various types of generalized pairwise fuzzy sets in the generalized fuzzy bitopological spaces. Several examples are given to investigate the generalized pairwise fuzzy sets and characterizations of generalized pairwise fuzzy sets are studied in

r-τ12-θ-GENERALIZED FUZZY CLOSED SETS IN SMOOTH BITOPOLOGICAL SPACES

Journal of New Theory, 2015
− In [34] we introduced the notion of r-(τi, τj)-θ-generalized fuzzy closed sets in smoothbitopological spaces by using (τiθ-fuzzy closure, denoted Cθon smooth bitopological spaces by using smooth supra topological space(X, τ12) which is generated from ...

TYPES OF FUZZY PAIRWISE S-COMPACTNESS MODULO SMOOTH IDEALS

Journal of New Theory, 2015
− In this paper, we introduce several types of fuzzy pairwise compactness and fuzzy pairwise compactness modulo a smooth ideal in smooth bitopological spaces by using the family of r(τi, τj)-fuzzy semi-open sets as cover.

r-t12-Fuzzy Semiopen Sets and Fuzzy Semi Continuity Mappings in Smooth Bitopological Spaces

Journal of New Results in Science, 2014
In this paper we introduce the notion of r-τsemiopen sets in smooth supra topological space (X, τ12) which isinduced from smooth bitopological space (X, τ1, τ2) [1].

Fuzzy $m$-structures $m$-open multifunctions and bitopological spaces

Boletim da Sociedade Paranaense de Matemática, 2018
In this paper we study different weak forms of open multifunctionsfrom a fuzzy topological space into a fuzzy $m$-space. Further we study the same from a fuzzy bitopological space into a fuzzy bitopological spaces.

On Lembda Gamma- Set in Fuzzy Bitopological Spaces

Boletim da Sociedade Paranaense de Matemática, 2017
The aim of this paper is to introduce the concept of lambda operator of a fuzzy set in a fuzzy bitopological space.  Then we study (i, j)-fuzzy Lembda Gamma- set and its properties. Moreover we define (i, j)-fuzzy Lembda-closed set, (i, j)-fuzzy Lembda Gamma-closed set and (i, j)-fuzzy generalized closed set in fuzzy bitopological space.

On Generalized Compactness in Fuzzy Bitopological Spaces

European Journal of Pure and Applied Mathematics
The main objective of this research is to study some types of generalized closed sets in fuzzy bitopology including $(i,j)-g\alpha-cld$, $(i,j)-gs-cld$, $(i,j)-gp-cld$, and $(i,j)-g\beta-cld$. We then present basic theorems for determining their relationships and explain their properties, such as closure and interior.
