A new class between theta open sets and theta omega open sets [PDF]

open access: yesHeliyon, 2021
We define θN-closure operator as a new topological operator which lies between the θ-closure and the θω-closure. Some relationships between this new operator and each of θ-closure, θω-closure, and usual closure are obtained.

𝐿-open sets and 𝐿 ∗ -open sets [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2020
As new classes of generalized open sets and generalized continuous functions, the notions of 𝐿-open sets, 𝐿 ∗ -open sets, 𝐿-continuous functions, 𝐿 ∗ -continuous functions and weakly 𝐿 ∗ -continuous functions are introduced and investigated. It is

Between μ-b-open sets and μ-β-open sets in generalized topological spaces [PDF]

open access: yesHeliyon, 2023
We introduce and study a new class of generalized open sets in generalized topological spaces, called μ‾-open sets. μ‾-open sets are strictly placed between μ-b-open sets and μ-β-open sets.

Between Open Sets and Semi-Open Sets

open access: yesUniversitas Scientiarum, 2018
We introduce and investigate ωs-open sets as a new class of sets which lies strictly between open sets and semi-open sets. Then we use ωs-open sets to introduce ωs -continuous functions as a new class of functions between continuous functions and semi ...

On a class of sets between a-open sets and gδ-open sets

open access: yesRatio Mathematica, 2020
In this paper, a new class of sets called Da-open sets are introduced and investigated with the help of gδ-open and δ-closed sets. Relationships between this new class and other related classes of sets are established and as an application Da-continuous ...

Between the Classes of Soft Open Sets and Soft Omega Open Sets

open access: yesMathematics, 2022
In this paper, we define the class of soft ω0-open sets. We show that this class forms a soft topology that is strictly between the classes of soft open sets and soft ω-open sets, and we provide some sufficient conditions for the equality of the three ...

Open-independent, open-locating-dominating sets [PDF]

open access: yesElectronic Journal of Graph Theory and Applications, 2017
A distinguishing set for a graph G = (V, E) is a dominating set D, each vertex $v \in D$ being the location of some form of a locating device, from which one can detect and precisely identify any given "intruder" vertex in V(G).

Cocompact Open Sets and Continuity [PDF]

open access: yesAbstract and Applied Analysis, 2012
Compact subsets of a topological space are used to define coc-open sets as new generalized open sets, and then coc-open sets are used to define (coc)∗-open sets as another type of generalized open sets.

On Fuzzy Sp-Open Sets [PDF]

open access: yesAdvances in Fuzzy Systems, 2011
A new class of generalized fuzzy open sets in fuzzy topological space, called fuzzy sp-open sets, are introduced, and their properties are studied and the relationship between this new concept and other weaker forms of fuzzy open sets we discussed ...

On -open sets

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences
This study investigates new concepts in grill topological spaces by employing specified sets in which the α-open sets are defined. Many scholars, such as Choquet, who is considered the first to lay the foundation stone for the concept of a grill and ...
