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

open access: yesJournal 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 ...

Soft Closed Sets on Soft Bitopological Space

open access: yesJournal of New Results in Science, 2014
Soft set theory was introduced by Molodtsov as ageneral mathematical tool for dealing with problems that containuncertainity. In this paper, on soft bitopological space, we definesoft closed sets; soft α-closed, soft semi-closed, soft pre-closed,regular ...

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

open access: yesJournal 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].

On Some Generalized Open Sets in Ideal Bitopological Spaces

open access: yesJournal of New Theory, 2020
In this article, we introduce and study the concepts of \gammaij- I -sets, \gammaij - preI -open sets, and \gammaij -b-I -open sets by generalizing (i,j)-I-open, (i,j)-preI-open, and (i,j)-bI- open sets, respectively, in ideal bitopological spaces with ...

ON SOME BITOPOLOGICAL SEPARATION AXIOMS

open access: yesJournal of New Theory, 2016
Abstaract−Fletcher et al. [1] introduced the concept of pairwise compactness for bitopological spaces. Reilly extended this concept to a larger class of bitopological spaces, called pairwise Lindel¨of spaces.

On Pairwise Semi-p-separation Axioms in Bitopological Spaces

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2017
In this paper, we define a new type of pairwise separation axioms called pairwise semi-p- separation axioms in bitopological spaces, also we study some properties of these spaces and relationships of each one with the ordinary separation axioms in the ...
