Graph theory, a branch of mathematics, studies the relationships between entities using
vertices and edges. Uncertain Graph Theory has emerged within this field to model the …

In this paper, we define soft ω-open sets and strongly soft ω-open sets as two new classes of
soft sets. We study the natural properties of these types of soft sets and we study the validity …

Weak forms of ω-open sets and decompositions of continuity Page 1 EUROPEAN JOURNAL OF

Soft rg ω-closed sets are introduced as a new class of soft sets that strictly contain the
classes of soft rg-closed sets and soft g ω-closed sets. Furthermore, the behavior of soft rg ω …

The purpose of this paper is to study 𝜔-continuous multifunctions. Basic characterizations,
preservation theorems and several properties concerning upper and lower 𝜔-continuous …

We extend the notion of omega open set in ordinary topological spaces to generalized
topological spaces. We obtain several characterizations of omega open sets in generalized …

The purpose of this paper is to introduce a new class of sets called semi-$\omega $-open
which lies between the class of $\alpha $-$\omega $-open sets and the class of $\beta …

A new weak form of both slightly continuous and ω-continuous, called slightly ω-continuous,
is introduced and studied. Furthermore, basic properties and preservation theorems of …

Abstract In 1994, Julian Dontchev called a function f of one topological space X to another Y
to be contra continuous if, for each open subset V of Y, the inverse image f-1 [V] is a closed …
