The concept of generalized open sets in generalized topological spaces was introduced by
A. Csaszar [6, 7]. In this paper, we introduce the concept of γ*-semi-open sets and …

In this paper, we define a new axiom called γ-s*-regularity. It is interesting to mention that
this axiom is a generalization of the axiom of s-regularity [11] as well as semi-regularity [4] …

We define and study the properties of γ-nbd, γ-nbd base at x, γ-closed nbd, γ-limit point, γ-
derived set, γ-isolated point, γ-derived set, γ-convergent point and γ-regular space …

In this paper, we continue studying the properties of γ∗-semi-open sets in topological
spaces introduced by S. Hussain, B. Ahmad and T. Noiri [8]. We also introduce and discuss …

We introduce and explore generalized open sets namely γ-pre-open and γ-b-open sets in
topological spaces. We also explore and investigate the properties and characterizations of …

The concept of generalized open sets in generalized topological spaces was introduced by
A. Csaszar [7, 8]. In this paper, we introduce a class of topological spaces called γ-s-closed …
