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

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.

On some spaces via topological ideals

Open Mathematics, 2023
Our main purpose is to introduce and investigate the concepts of some forms of spaces via topological ideals. Some characterizations of some forms of spaces via topological ideals are established.

Products of effective topological spaces and a uniformly computable Tychonoff Theorem [PDF]

, 2013
This article is a fundamental study in computable analysis. In the framework of Type-2 effectivity, TTE, we investigate computability aspects on finite and infinite products of effective topological spaces.

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.

Modal Logic Axioms Valid in Quotient Spaces of Finite CW-Complexes and Other Families of Topological Spaces

International Journal of Mathematics and Mathematical Sciences, 2016
In this paper we consider the topological interpretations of L□, the classical logic extended by a “box” operator □ interpreted as interior. We present extensions of S4 that are sound over some families of topological spaces, including particular point ...

A-topology for Minkowski space [PDF]

The Journal of the Australian Mathematical Society. Series B. Applied Mathematics, 1979
AbstractWe consider in this paper a topology (which we call the A-topology) on Minkowski space, the four-dimensional space–time continuum of special relativity and derive its group of homeomorphisms. We define the A-topology to be the finest topology on Minkowski space with respect to which the induced topology on time-like and light-like lines is one ...
