This paper is concerned with the concepts of upper and lower β\(⋆\)-continuous
multifunctions. In particular, several characterizations of upper and lower β\(⋆\)-continuous …

The purpose of this paper is to introduce two new classes of funct ions called α-I-
preirresolute functions and β-I-preirresolute functions in ideal topological spaces. Some …

Let mIO (X) be the family of ⋆-open (resp. α-I-open, pre-I-open, semi-I-open, β-I-open, etc.)
sets in an ideal topological space (X, Ï „, I). By using mIO (X), we introduce and investigate …

In this paper we introduce upper/lower mI-continuous multifunctions as a multifunction
defined on an ideal minimal space (X, m, I). We obtain some characterizations and several …

We introduce the notion of mIO (X)-structures determined by operators Int, Cl and Cl* on an
ideal topological space (X, τ, 그). By using mIO (X)-structures, we introduce and investigate a …

We introduce some weak types of open sub sets with ideals in supra. topological space
(supra. αI*-open, supra. SI*-open, supra. PI*-open, supra. βI*-open, supra. bI*-open) also …

The aim of this article is to introduce and study the concept of bI-open sets with respect to an
ideal in bitopological spaces and to investigate some properties. Moreover, the concept of bI …

The notions of pre-local function, semi-local functions and ${\alpha} $-local functions with
respect to a topology and an ideal are introduced, and several properties are investigated …
