More on Selective Covering Properties in Bitopological Spaces
Journal of Mathematics, 2021 In this study, we continue our investigation of selective covering properties in bitopological spaces. We discuss their behaviour under certain kinds of mappings.

Neutrosophic Bitopological Spaces [PDF]
Neutrosophic Sets and Systems, 2019 In this study, bitopological structure which is a more general structure than topological spaces is built on neutrosophic sets. The necessary arguments which are pairwise neutrosophic open set, pairwise neutrosophic closed set, pairwise neutrosophic ...

Some Subsets of Bitopological Spaces
International Journal of Analysis and Applications, 2023 In this paper, we introduce the notions of minimal u-ω-closed sets, maximal u-ω-open sets, u-ω-paraopen sets, u-ω-paraclosed sets, u-ω-mean open sets and u-ω-mean closed sets in bitopological spaces and obtain several characterizations and some of its ...

On r-Compactness in Topological and Bitopological Spaces
Axioms, 2023 This paper defines the so-called pairwise r-compactness in topological and bitopological spaces. In particular, several inferred properties of the r-compact spaces and their connections with other topological and bitopological spaces are studied ...

Preopenness Degree in RL-Fuzzy Bitopological Spaces
Abstract and Applied Analysis, 2022 Based on the concept of pseudocomplement, we introduce a new representation of preopenness of L-fuzzy sets in RL-fuzzy bitopological spaces. The concepts of pairwise RL-fuzzy precontinuous and pairwise RL-fuzzy preirresolute functions are extended and ...

Some Results of τ1τ2-δ Semiconnectedness and Compactness in Bitopological Spaces
Journal of Mathematics, 2018 We are going to establish some results of τ1τ2-δ semiconnectedness and compactness in a bitopological space. Besides, we will investigate several results in τ1τ2-δ semiconnectedness for subsets in bitopological spaces.

Pre-Open Sets In Minimal Bitopological Spaces
Journal of Kufa for Mathematics and Computer, 2015 Let be a topological space, let be an M-structure on then is called a minimal bitopological space. In this work, I am study pre-open sets in minimal bitopological spaces with some result and definitions separation axioms on minimal bitopological ...

On c-Compactness in Topological and Bitopological Spaces
Mathematics, 2023 The primary goal of this research is to initiate the pairwise c-compact concept in topological and bitopological spaces. This would make us to define the concept of c-compact space with some of its generalization, and present some necessary notions such ...

A Note on Some Generalized Closed Sets in Bitopological Spaces Associated to Digraphs
Journal of Applied Mathematics, 2012 Many investigations are undergoing of the relationship between topological spaces and graph theory. The aim of this short communication is to study the nature and properties of some generalized closed sets in the bitopological spaces associated to the ...

PREOPEN SETS IN SMOOTH BITOPOLOGICAL SPACES [PDF]
Communications of the Korean Mathematical Society, 2003 Summary: We introduce the notions of \((\mathcal T_i,\mathcal T_j)\)-fuzzy \((r,s)\)-preopen sets and fuzzy pairwise \((r,s)\)-precontinuous mappings in smooth bitopological spaces and then we investigate some of their characteristic properties.
