i-Open Sets and Separating Axioms Spaces [PDF]

مجلة التربية والعلم, 2018
The purpose of this paper is using a class of open sets called i-open sets [9] to study some classes of separating axioms spaces for open,  -open and semi-open sets. Further, we studied the relations between such spaces.

Semi separation axioms and hyperspaces

International Journal of Mathematics and Mathematical Sciences, 1981
In this paper examples are given to show that s-regular and s-normal are independent; that s-normal, and s-regular are not semi topological properties; and that (S(X),E(X)) need not be semi-T1 even if (X,T) is compact, s-normal, s-regular, semi-T2, and ...

Ϣ-Semi-p Open Set

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2023
Csaszar introduced the concept of generalized topological space and a new open set in a generalized topological space called -preopen in 2002 and 2005, respectively. Definitions of -preinterior and -preclosuer were given.

On ƞǤ_Ş-Compactness

Ibn Al-Haitham Journal for Pure and Applied Sciences
Open sets may be viewed as an extension of semi-open sets by applying the notions of semi-open sets and grill nano to nGs-open sets, with the following four goals in mind: The objective is to characterize nGs-open sets by examining and proving numerous ...

Applications of fuzzy bitopological semi-open sets

Malaya Journal of Matematik, 2020
The aim of this paper is to introduce and study the notions of fuzzy upper and lower \((i, j)\)-semilimit sets. Properties and basic relationships among fuzzy upper \((i, j)\)-semilimit set, fuzzy lower \((i, j)\)-semilimit set and fuzzy \((i, j)\)-semicontinuity are investigated.

Mean semi-open sets

Malaya Journal of Matematik
This article introduces a mean set that is also semi-open. Such a set contains a non-void proper semi-open set and also contained in another proper semi-open set. We examine some properties of mean semi-open sets and also their complements. Furthermore, we investigate the behavior of such sets when they are also minimal and maximal.
