Pairwise Generalized Semi Operation Continuous Mappings [PDF]

Assiut University Journal of Multidisciplinary Scientific Research
Our aim of this paper is to continue the study of operations on generalized semi open sets in bitopological spaces which was initiated in 2024 by Khedr et al. [12].

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.

On weakly b-continuous functions in bitopological spaces - doi: 10.4025/actascitechnol.v35i3.15612

Acta Scientiarum: Technology, 2013
In this article we introduce the notion of weakly b–continuous functions in bitopological spaces as a generalization of b–continuous functions. We prove several properties of these functions.

Superextension as bitopological space

Izvestiya Instituta Matematiki i Informatiki. Udmurt. Gos. Univ., 2017
The author studies some properties of a bitopological space and its subspaces that appear on the superextension of a topological space \(X\). The superextension of \(X\) is the set of all maximal linked systems of closed subsets of \(X\). Two topologies on the superextension of \(X\) are considered: one of Wallman type and the other of Stone type.

Bitopological and topological ordered k-spaces

Topology and its Applications, 2005
La notion de \(k\)-espace, pour les espaces topologiques, est bien connue et a de nombreuses utilisations. Les auteurs développent une notion analogue dans la catégorie des espaces bitopologiques, qu'ils nomment \(k\)-biespace. Ils considèrent aussi les espaces munis à la fois d'une topologie et d'une relation d'ordre, et introduisent la classe des \(k\

Partial metrizability in value quantales

Applied General Topology, 2004
Partial metrics are metrics except that the distance from a point to itself need not be 0. These are useful in modelling partially defined information, which often appears in computer science.

N-Fuzzy BI-Topological Space and Separation Axioms

Journal of New Theory, 2018
In this article, we introduced N-fuzzy bi-topological space by using the conceptsof fuzzy bi-topological space. We further define some basic properties of N-fuzzy bi-topologicalspaces, secondly we study the concepts of natural separation axioms of bi ...

Soft Bitopological Spaces

International Journal of Computer Applications, 2014
In this paper, introduce and study the concept of soft bitopological spaces which are defined over an initial universe with a fixed set of parameters. Also introduce and investigate some new separation axioms called pairwise soft T0, pairwise soft T1 and pairwise soft T2 spaces and study some of their basic properties in soft bitopological spaces.

On Strong $(i,j)$-Semi$^{*}$-$\Gamma $-Open Sets in Ideal Bitopological Space

Journal of New Theory
In this study, we introduce the concepts of $(i,j)$-semi$^{*}$-$\Gamma $-open sets within the context of ideal bitopological spaces. This concept is demonstrated to be weaker than the established the notion of $(i,j)$-semi-$\Gamma $-open sets ...
