On Soft SIgδs-closed sets [PDF]
E3S 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.

Applications of some modified open sets in r-neighbourhood spaces with ideals [PDF]
E3S Web of Conferences, 2023 The purpose of this paper is to introduce r-a-open sets, r-semi open sets and r-pre open sets in ideal r-neighbourhood space. We also discuss their properties, characterizations and relations with existing notions with suitable examples.

On a locally compact monoid of cofinite partial isometries of ℕ with adjoined zero
Topological Algebra and its Applications, 2022 Let 𝒞ℕ be a monoid which is generated by the partial shift α : n↦n +1 of the set of positive integers ℕ and its inverse partial shift β : n + 1 ↦n. In this paper we prove that if S is a submonoid of the monoid Iℕ∞ of all partial cofinite isometries of ...

On ω*-open sets and decomposition of continuity
Topological Algebra and its Applications, 2022 In this paper our main interest is to introduce a new topology on an ideal topological space.We have studied some properties of this newly defined topology.

Demonstratio Mathematica, 2020 Many mathematicians defined and studied soft separation axioms and soft continuity in soft spaces by using ordinary points of a topological space X. Also, some of them studied the same concepts by using soft points.

Open Mathematics, 2021 This work studies a new version of normality called epi-quasi normality, which lies between epi-normality and epi-mild normality. In this paper, we investigate this property and present some examples that illustrate the relationships between epi-quasi ...

Delta and Theta Generalized Closed Sets in Bitopological Spaces [PDF]
Assiut University Journal of Multidisciplinary Scientific Research, 2016 In this paper we introduce new two types of generalized closed sets in bitopologicalspaces and study some of it's properties and it's relations with other kinds ofgeneralized closed sets.

Regularity and normality in hereditary bi m-spaces
Demonstratio Mathematica, 2022 Quite recently, a new minimal structure mH⋆{m}_{H}^{\star } and an mnmn-ℋg{{\mathcal{ {\mathcal H} }}}_{g}-closed set have been introduced in a previous study [T. Noiri and V.

More properties of generalized open sets in generalized topological spaces
Demonstratio Mathematica, 2022 Sarsak [M. S. Sarsak, On some properties of generalized open sets in generalized topological spaces, Demonstr. Math. 46 (2013), no. 2, 415–427] studied some properties of generalized open sets in generalized topological spaces (GTSs); the primary purpose
