On Neutrosophic Semi Alpha Open Sets [PDF]
Neutrosophic Sets and Systems, 2017 In this paper, we presented another concept of neutrosophic open sets called neutrosophic semi-alfa-open sets and studied their fundamental properties in neutrosophic topological spaces.

Mathematics, 2021 In this paper, we introduce the class of soft semi ω-open sets of a soft topological space (X,τ,A), using soft ω-open sets. We show that the class of soft semi ω-open sets contains both the soft topology τω and the class of soft semi-open sets ...

A note on some applications of semi‐open sets [PDF]
International Journal of Mathematics and Mathematical Sciences, 1996 The object of the present paper is to study the well known notions of semi‐closure, semiinterior, semi‐frontier and semi‐exterior of a set using the concept of semi‐open sets. A semi‐isolated point of a set is also defined and studied.

Semi-open sets in biclosure spaces
Discussiones Mathematicae - General Algebra and Applications, 2009 The aim of this paper is to introduce and study semi-open sets in biclosure spaces. We define semi-continuous maps and semi-irresolute maps and investigate their behavior. Moreover, we introduce pre-semiopen maps in biclosure spaces and study some of their properties.

On semi-open sets and Feebly open sets in generalized topological spaces
Proyecciones (Antofagasta), 2019 In this paper, we introduce the notion of semi-open sets and feebly open sets in generalized topological spaces. Several properties of these notions are discussed. Also this paper considers (semi and feebly)-separation axioms for generalized topological spaces.

Neutrosophic Biminimal Semi-Open Sets
, 2023 In this article, we introduced the notions of N j mX-semi-open sets, semiinterior and semi-closure operators in neutrosophic biminimal structures. We investigate some basic properties of such notions. Also, we introduced the notion of N j mX-semicontinuous maps and study characterizations of N j mX-semi-continuous maps by using the semi-interior and ...

$r$-fuzzy regular semi open sets in smooth topological spaces [PDF]
Sahand Communications in Mathematical Analysis, 2017 In this paper, we introduce and study the concept of $r$-fuzzy regular semi open (closed) sets in smooth topological spaces. By using $r$-fuzzy regular semi open (closed) sets, we define a new fuzzy closure operator namely $r$-fuzzy regular semi interior

Nano SC-Open Sets in Nano Topological Spaces
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2023 The objective of this paper is to define and introduce a new type of nano semi-open set which called nano -open set as a strong form of nano semi-open set which is related to nano closed sets in nano topological spaces.

Semi-precontinuous functions and properties of generalized semi-preclosed sets in topological spaces [PDF]
International Journal of Mathematics and Mathematical Sciences, 2002 Andrijević (1986) introduced the class of semi-preopen sets in topological spaces. Since then many authors including Andrijević have studied this class of sets by defining their neighborhoods, separation axioms and functions. The purpose of this paper is
