On ωθ˜-µ-Open Sets in Generalized Topological Spaces

Publikováno v: International Journal of Analysis and Applications, Vol 20, Pp 72-72 (2022)

In this paper analogous to [1], we introduce a new class of sets called ωθ˜-µ-open sets in generalized topological spaces which lies strictly between the class of θ˜µ-open sets and the class of ω-µ-open sets. We prove that the collection of

Weakly m-compact via a hereditary class

Autor: Abdo Qahis, Heyam Hussain AlJarrah, Takashi Noiri

Publikováno v: Boletim da Sociedade Paranaense de Matemática, Vol 39, Iss 3 (2020)

The aim of this paper is to introduce and study some types of m-compactness with respect to a hereditary class called weakly mH-compact spaces and weakly mH-compact subsets. We will provide several characterizations of weakly mH-compact spaces and in

Strongly path-confluent mappings

Autor: Abdo Qahis, Mohd. Salmi Md. Noorani

Publikováno v: Applied General Topology, Vol 14, Iss 1, Pp 85-95 (2013)

In this paper, we introduce a new class of path-confluent mapping, called strongly path-confluent maps. We discuss and study some characterizations and some basic properties of this class of mappings. Relations between this class and some other exist

On Quasi-ω-Confluent Mappings

Autor: Abdo Qahis, Mohd. Salmi Md. Noorani

Publikováno v: International Journal of Mathematics and Mathematical Sciences, Vol 2011 (2011)

We introduce a new class of mappings called quasi-ω-confluent maps, and we study the relation between these mappings, and some other forms of confluent maps. Moreover, we prove several results about some operations on quasi-ω-confluent mappings suc

New forms of -compactness with respect to hereditary classes

Autor: Abdo Qahis

Publikováno v: Boletim da Sociedade Paranaense de Matemática, Vol 37, Iss 1, Pp 21-31 (2019)

A hereditary class on a set X is a nonempty collection of subsets closed under heredity. The aim of this paper is to introduce and study strong forms of u-compactness in generalized topological spaces with respect to a hereditary class, called SuH-co

$\mu$-Paracompactness via Hereditary Classes

Autor: Abdo Qahis, Takashi Noiri

Publikováno v: Missouri J. Math. Sci. 32, iss. 1 (2020), 21-31

The notion of paracompactness in generalized topology is introduced and studied in [5]. In this paper, we introduce and investigate the notion of $\mu$-paracompact spaces with respect to a hereditary class $\mathcal{H}$, which is a generalization of
