On Some Closed Sets and Low Separation Axioms Via Topological Ideals
Social Science Research Network, 2022This paper deals with the concepts of Λp(⋆)-sets and (Λ, p(⋆))-closed sets which are defined by utilizing the notions of pre-I -open sets and pre-I -closed sets.

Fibrewise totally separation axioms
Journal of Interdisciplinary Mathematics, 2022The purpose of this paper is to introduce and study fiberwise totally separation axioms which are generlization of separation axioms in ordinary topology called fibrewise totally T 0, (resp., T 1, R 0, Hausdorff, functionally Hausdorff, regular ...

On Neutrosophic Generalized Alpha Generalized Separation Axioms
International journal of neutrosophic science, 2022The paper provided a new notion of neutrosophic separation axioms as neutrosophic gαg-Ri-space neutrosophic gαg-Tj-space (note that the indexes i j are natural numbers of the spaces R T are from 0 to 1 from 0 to 2 alternately).

Computable soft separation axioms
Mathematical Structures in Computer Science, 2023AbstractSoft sets were introduced as a means to study objects that are not defined in an absolute way and have found applications in numerous areas of mathematics, decision theory, and in statistical applications. Soft topological spaces were first considered in Shabir and Naz ((2011).

Some types of fuzzy separation axioms in fuzzy topological space on fuzzy set
PROCEEDING OF THE 1ST INTERNATIONAL CONFERENCE ON ADVANCED RESEARCH IN PURE AND APPLIED SCIENCE (ICARPAS2021): Third Annual Conference of Al-Muthanna University/College of Science, 2022The aim of this paper to introduce and study fuzzy 𝛿 -open set and the relations of some other class of fuzzy open sets like (R-open set, 𝜃 -open set, 𝛾 -open set, ∆ -open set), introduce and study some types of fuzzy 𝛿 -separation axioms in fuzzy ...

A Definition of Separation Axiom
Canadian Mathematical Bulletin, 1974Several separation axioms, defined in terms of continuous functions, were examined by van Est and Freudenthal [3], in 1951. Since that time, a number of new topological properties which were called separation axioms were defined by Aull and Thron [1], and later by Robinson and Wu [2], This paper gives a general definition of separation axiom, defined ...

Applied Categorical Structures, 1994
First is shown that if \({\mathcal B}\) is an epireflective subcategory of all locales, and \({\mathcal B}\) is generated by a nice locale \(B\), then every \(A\in {\mathcal B}\) containing \(B\) as a retract is an Isbell locale (i.e., it is a regular cogenerator for a certain subcategory).

The classical (point-set) topology concerns points and relationships between points and subsets. Omitting points and considering only the structure of open sets leads to the notion of frames, that is, a complete lattice satisfying the dis- tributive law b ∧ A = {b ∧ a | a ∈ A}, the crucial concept of point-free topology.
