Sum of Soft Topological Spaces

Mathematics, 2020
In this paper, we introduce the concept of sum of soft topological spaces using pairwise disjoint soft topological spaces and study its basic properties.

ϱ- TOPOLOGICAL OPERATORS IN TOPOLOGICAL SPACES

Science Journal of University of Zakho, 2023
Operation Approach on a new class of topological spaces with -open subsets was called a -open set. In this article, we examined some basic properties of open sets such as closure, , limit points, derived sets, neighbourhood, interior, exterior, boundary,

Topology and the Visualization of Space

Symmetry, 2014
Overlapping patterns provide the diagrammatics for four-dimensional space. If these patterns are three-dimensional lattices, and if one imagines them extended in three-dimensional space, then the diagram makes a model of physical space.

Construction of 3D Indoor Topological Models Based on Improved Face Sorting

ISPRS International Journal of Geo-Information
Indoor location-based services and applications need to obtain information about the indoor spatial layouts and topological relationships of indoor spaces. The 3D city modeling data standard CityGML describes the indoor geometric and semantic information

Primal topological spaces

Boletim da Sociedade Paranaense de Matemática
The purpose of this paper is to introduce a new structure called primal. Primal is the dual structure of grill. Like ideal, the dual of filter, this new structure also generates a new topology named primal topology. We introduce a new operator using primal, which satisfies Kuratowski closure axioms.

Functional product topology: A common framework of the topological sum, the product topology and the functional topology of pointwise convergence

Journal of Hebei University of Science and Technology, 2015
Based on the topological sum, for X being a discrete topological space, we prove that the product topology generated by some topological spaces is equal to the topology of pointwise convergence related to X.

Local homogeneity in fuzzy topological spaces

International Journal of Mathematics and Mathematical Sciences, 2006
Three types of local homogeneity in L-topological spaces are introduced and studied, and each is characterized and proved to be a good extension of local homogeneity in ordinary topological spaces. Many implications concerning them are introduced.

Topological Structure of Vague Soft Sets

Abstract and Applied Analysis, 2014
We introduce vague soft topological spaces which are defined over an initial universe with a fixed set of parameters. The notions of vague soft open sets, vague soft closed sets, vague soft interior, vague soft closure, and vague soft boundary are ...

Countable Fuzzy Topological Space and Countable Fuzzy Topological Vector Space

Journal 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
