Countable Fuzzy Topological Space and Countable Fuzzy Topological Vector Space

open access: yesJournal of Mathematical and Fundamental Sciences, 2015
This paper deals with countable fuzzy topological spaces, a generalization of the notion of fuzzy topological spaces. A collection of fuzzy sets F on a universe X forms a countable fuzzy topology if in the definition of a fuzzy topology, the condition of

A New Perspective On Soft Topology

open access: yesHittite Journal of Science and Engineering, 2018
In this paper, we approach the concept of soft topology with a different perspective. We define a soft topological space over given initial topological universe as a parameterization of subspaces of a topological space.

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.

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.

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 ...

Space-time Uncertainty Principle from Breakdown of Topological Symmetry [PDF]

open access: yes, 1997
Starting from topological quantum field theory, we derive space-time uncertainty relation with respect to the time interval and the spatial length proposed by Yoneya through breakdown of topological symmetry in the large N matrix model.

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 ...

Door spaces on N-topology

open access: yesRatio Mathematica, 2023
In this article, we explore the idea of door space on -topological space. Here, we discuss which door spaces in this space are related with  submaximal. The equivalent conditions shows how it connects a -topological property. Also, we derive various door
