On Soft SIgδs-closed sets [PDF]

open access: yesE3S Web of Conferences, 2023
In this paper, we introduce some new notions called soft SIgδs - closed sets, soft SIgδs - open sets. We obtain several characterizations and some of their properties. Also, we investigate its relationship with other types of sets.

A DECOMPOSITION OF CONTINUITY ON F*– SPACES AND MAPPINGS ON SA*– SPACES

open access: yesSüleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2009
: An ideal topological space (X,Ï„,I) is said to be an F* – space if A=Cl*(A) for every open set A ⊂ X. In this paper, a decomposition of continuity on F* – spaces is introduced.

On the Borel Classes of Set-Valued Maps of Two Variables

open access: yesAnnales Mathematicae Silesianae, 2020
Using the Borel classification of set-valued maps, we present here some new results on set-valued maps which are similar to some of the well known theorems on functions due to Lebesgue and Kuratowski.

On ω*-open sets and decomposition of continuity

open access: yesTopological Algebra and its Applications, 2022

On some spaces via topological ideals

open access: yesOpen Mathematics, 2023
Our main purpose is to introduce and investigate the concepts of some forms of spaces via topological ideals. Some characterizations of some forms of spaces via topological ideals are established.

Some Analogues of Topological Groups

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2021
Let (G, ∗) be a group and τ be a topology on G. Let τα = {A ⊆G : A ⊆ Int(Cl(Int(A)))}, g ∗ τ = {g ∗ A : A ∈ τ} for g ∈ G. In this paper, we establish two relations between G and τ under which it follows that g ∗ τ ⊆ τα and g ∗ τα ⊆ τα, designate them by ...

A Separately Continuous Function Not Somewhat Continuous

open access: yesAnnales Mathematicae Silesianae, 2022
We construct a separately continuous function f : ℚ × ℚ → [0; 1] and a dense subset D ⊆ ℚ × ℚ such that f[D] is not dense in f[ℚ × ℚ], in other words, f is separately continuous and not somewhat (feebly) continuous.

More On Weak Soft Axioms

open access: yesMoroccan Journal of Pure and Applied Analysis, 2020
In this paper, we continue studying the properties of weak soft axioms discussed and studied in [8]. We initiate and explore soft semi-R0 spaces at soft point in terms of soft semi-open sets and study its characterizations and properties.

Properties Of New Classes Of ω-µ-Sets In Gts

open access: yes, 2023
The notions of ω-µ-closed sets and ω-µ-open sets in generalized topological space were introduced and studied by Al Ghour and Zareer. In this paper, we introduce new classes of ω-µ-open sets and continuous functions in topological spaces and study the ...

Sum of the spaces on ordered setting

open access: yesMoroccan Journal of Pure and Applied Analysis, 2020
One of the divergences between topology and ordered topology is that some topological concepts such as separation axioms and continuous maps are defined using open neighborhoods or neighborhoods without any difference, however, they are distinct on the ...
