On Cubic Interval Vague Sets and Cubic Interval Vague Topological Spaces

open access: yesScience Journal of University of Zakho, 2022
 advance a modern extension formation of cubic vague sets identified as cubic interval vague sets (CIVSs).  similarly describe the idea of  cubic interval vague sets (ICIVSs)    cubic interval vague sets (ECIVSs) by examples  debate their exciting ...

A new approach to nearly paracompact spaces

open access: yesМатематичні Студії, 2023
The pre-open sets are a generalization of open sets of topological spaces. In this paper, we introduce and study a notion of po-paracompact spaces via pre-open sets on topological spaces.

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

open access: yes, 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.

On the Structure of Topological Spaces

open access: yesAxioms, 2022
The structure of topological spaces is analysed here through the lenses of fibrous preorders. Each topological space has an associated fibrous preorder and those fibrous preorders which return a topological space are called spatial.

Relative Smooth Topological Spaces

open access: yesAdvances in Fuzzy Systems, 2009
In 1992, Ramadan introduced the concept of a smooth topological space and relativeness between smooth topological space and fuzzy topological space in Chang's (1968) view points. In this paper we give a new definition of smooth topological space.

Topological Rough Groups

open access: yesTopological Algebra and its Applications, 2016
The concept of topological group is a simple combination of the concepts of abstract group and topological space. The purpose of this paper is to combine the concepts of topological space and rough groups; called topological rough groups on an ...

Topological Conformal Dimension [PDF]

open access: yes, 2015
We investigate a quasisymmetrically invariant counterpart of the topological Hausdorff dimension of a metric space. This invariant, called the topological conformal dimension, gives a lower bound on the topological Hausdorff dimension of quasisymmetric ...

A Hybrid Approach to Micro Vague Topological Space via Neutrosophic Topological Space [PDF]

open access: yesNeutrosophic Sets and Systems
Plenty of topologists are exploring and discovering multiple forms of topological spaces. The chief objective of the current enquiry is to establish and evaluate an original hybrid topological space named Neutrosophic Micro Vague Topological Space. When

Closed subsets of compact-like topological spaces

open access: yesApplied General Topology, 2020
We investigate closed subsets (subsemigroups, resp.) of compact-like topological spaces (semigroups, resp.). We show that each Hausdorff topological space is a closed subspace of some Hausdorff ω-bounded pracompact topological space and describe open ...

Type space on a purely measurable parameter space [PDF]

open access: yes, 2005
Several game theoretical topics require the analysis of hierarchical beliefs, particularly in incomplete information situations. For the problem of incomplete information, Hars´anyi suggested the concept of the type space.
