Via semi α-regular weakly in ideal topological spaces on continuous and irresolute functions

In this paper, we apply the notion of $e$-$\I$-open sets \cite{Wadei6} in ideal topological spaces to present and study new classes of functions called contra $e$-$\I$-continuous functions, almost-$e$-$\I$-continuous, almost contra-$e$-$\I$-continuous, and almost weakly-$e$-$\I$-continuous along with their several properties, characterizations and mutual relationships. Relationships between their new classes and other classes of functions are established and some characterizations of their new classes of functions are studied. Further, we introduce new types of graphs, called $e$-$\I$-closed, contra-$e$-$\I$-closed, and strongly contra-$e$-$\I$-closed graphs via $e$-$\I$-open sets. Several characterizations and properties of such notions are investigated.

A new class of functions, called slightly generalized β-continuous functions is introduced.Basic properties of slightly generalized β-continuous functions are studied.The class of slightly generalized βcontinuous functions properly includes the class of slightly β-continuous functions and generalized β-continuous functions.Also, by using slightly generalized β-continuous functions, some properties of domain/range of functions are characterized.

In this paper, we introduce the concept of generalized double fuzzy semi-basically disconnected space and related notions such as (r, s)-generalized fuzzy semiopen-F σ sets, (r, s)-generalized fuzzy semiclosed-G δ sets, generalized double fuzzy semi * -open function, generalized double fuzzy semi * -continuous function and generalized double fuzzy semi * -irresolute function. Some interesting properties and characterizations of the concepts introduced are studied.

In this paper, we introduce two new classes of continuous functions in topological spaces called almost Ip-continuous and weakly Ip-continuous functions. We obtain several characterizations of them and some of their properties. Also, we investigate their relationships with some other types of functions.

This study analyzes the characteristics and functioning of Sg∗-functions, Sg∗-homeomorphisms, and Sg∗#-homeomorphisms in generalized topological spaces (GTS). A few important points to emphasize are Sg∗-continuous functions, Sg∗-irresolute functions, perfectly Sg∗-continuous, and strongly Sg∗-continuous functions in GTS and generalized primal topological spaces (GPTS). Some specific kinds of Sg∗ functions, such as Sg∗-open mappings and Sg∗-closed mappings, are discussed. We also analyze the GPTS, providing a thorough look at the way these functions work in this specific context. The goal here is to emphasize the concrete implications of Sg∗ functions and to further the theoretical understanding of them by merging different viewpoints. This work advances the area of topological research by providing new perspectives on the behavior of Sg∗ functions and their applicability in various topological settings. The outcomes reported here contribute to our theoretical understanding and establish a foundation for further research.

Cauchy-subregular functions vis-à-vis different types of continuity

In this paper, we investigate some properties of a*-I-open set [3] and Asemi*-I-open sets defined in [3] in ideal topological space. The relationships of other related classes of sets are investigated. Also, a new decomposition of continuous functions is obtained by using δβA-I-open and SA*-set functions in an ideal topological space.

In this paper, a generalized class of ??*called weakly Ir?-open sets in ideal topological spaces is introduced and the notion of weakly Ir?-closed sets in ideal topological spaces is studied. The relationships of weakly Ir?-closed sets and various properties of weakly Ir?-closed sets are investigated.

In this paper we introduce and investigate some properties of semi*- I-open sets, pre*-I-open sets and e-I-open sets in ideal topological spaces. Moreover, some relationships among semi*-I-open sets, e-I-open sets and pre*-I-open sets in ideal topological spaces are established. Finally, we obtain the decompositions of continuity.

We introduce new classes of sets called a* -I -open,A-β-I-open sets, A-pre* -I-open sets, strongly T-I -sets, A-β-T-I-sets, strongly BA -I -sets, BA -I -sets, and δβA -I -open sets in ideal topological spaces. Using these sets, to obtain decompositions of continuity in an ideal topological space.

In this paper, we introduce the notion of an \((i,j)\)-\(\mathcal{N}\)-\(\beta\)-open set which is a generalization of an \((i,j)\)-\(\beta\)-open set in a bitopological space. Also, we investigate some of its properties and characterizations. Besides, we prove that a pairwise \((i, j)\)-\(\mathcal{N}\)-\(\beta\)-open cover that has a finite (countable) subcover is equivalent to a pairwise \(\beta\)-compact (\(\beta\)-Lindel\"{ö}f) space. Finally, we introduce an \((i, j)\)-\(\mathcal{N}\)-\(\beta\)-continuous function and an \((i, j)\)-\(\mathcal{N}\)-\(\beta\)-irresolute function and obtain some of their properties.

An ideal topological space is a triplet (X, τ, ℑ), where X is a nonempty set, τ is a topology on X, and ℑ is an ideal of subsets of X. In this paper, we introduce L∗-perfect, R∗-perfect, and C∗-perfect sets in ideal spaces and study their properties. We obtained a characterization for compatible ideals via R∗-perfect sets. Also, we obtain a generalized topology via ideals which is finer than τ using R∗-perfect sets on a finite set.

We introduced and studied some new classes of functions called (e*, s)-continuous functions, (e, s)-continuous functions and (a, s)-continuous functions. These new notions of functions generalize the class of almost contra-super-continuous functions. Some properties and several characterizations of these types of functions are obtained. We investigate the relationships between these classes of functions and other classes of non-continuous functions. .

The main aim of this paper is to study new class of continuous function is called – continuous function. for this aim, the nation of - open and pre – open sets and - compact space are introduced. and we shall study the relationship between – continuous and pc– continuous functions.

In this research we introduce h-local functions by using h-open sets in an ideal topological space (X, tau, I). Some properties and characterizations of the h-local functions are studied. Also, we introduce and research the notions of I_{{s^*}g}-h-closed and I_{g}-h-closed sets in an ideal topological space. Additionally, Cl^*_h is defined and its properties are examined.
