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

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 ...

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 ...
