On Characterizations of ∗-Hyperconnected Ideal Topological Spaces

Journal of Mathematics, 2020
In the present paper, some characterizations of ∗-hyperconnected ideal topological spaces are investigated. Moreover, we introduce the notion of S∗-ℐ-hyperconnected ideal topological spaces.

Neutrosophic Vague Topological Spaces [PDF]

Neutrosophic Sets and Systems, 2019
The term topology was introduced by Johann Beredict Listing in the 19th century. Closed sets are fundamental objects in a topological space. In this paper, we use neutrosophic vague sets and topological spaces and we construct and develop a new concept

Two preservation results for countable products of sequential spaces [PDF]

, 2007
We prove two results for the sequential topology on countable products of sequential topological spaces. First we show that a countable product of topological quotients yields a quotient map between the product spaces.

A Study on Continuity functions in Neutro-Topological Spaces [PDF]

Neutrosophic Sets and Systems
The specific purpose of this study is to define continuity of mappings in neutro-topological spaces using neutro-open and neutro-closed sets and analyze the properties of continuous functions that are true in classical topological spaces in the neutro ...

On some spaces via topological ideals

Open Mathematics, 2023

On Neutrosophic Crisp Topology via N-Topology [PDF]

Neutrosophic Sets and Systems, 2018
In this paper, we extend the neutrosophic crisp topological spaces into N-neutrosophic crisp topological spaces (Nnc-topological space). Moreover, we introduced new types of open and closed sets in N-neutrosophic crisp topological spaces. We also present

The non-existence of a universal topological type space [PDF]

, 2010
The concept of types was introduced by Harsányi[8]. In the literature there are two approaches for formalizing types, type spaces: the purely measurable and the topological models.

α-Topological Vector Spaces

Science Journal of University of Zakho, 2017
The main objective of this paper is to present the study of α-topological vector spaces. α-topological vector spaces are defined by using α-open sets and α-irresolute mappings.

Topological Up-Algebras

Discussiones Mathematicae - General Algebra and Applications, 2019
In this paper, we introduce the notion of topological UP-algebras and several types of subsets of topological UP-algebras, and prove the generalization of these subsets.

Neutrosophic Nano Semi-Frontier [PDF]

Neutrosophic Sets and Systems, 2020
Smarandache presented and built up the new idea of Neutrosophic set from the Intuition istic fuzzy sets. A.A. Salama presented Neutrosophic topological spaces by utilizing the Neutro sophic sets.
