On Neutrosophic Crisp Topology via N-Topology [PDF]

open access: yesNeutrosophic 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

On some spaces via topological ideals

open access: yesOpen 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.

α-Topological Vector Spaces

open access: yesScience 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

open access: yesDiscussiones 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.

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

open access: yesInternational 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 ...

Nearly Soft Menger Spaces

open access: yesJournal of Mathematics, 2020
In this paper, we define a weak type of soft Menger spaces, namely, nearly soft Menger spaces. We give their complete description using soft s-regular open covers and prove that they coincide with soft Menger spaces in the class of soft regular⋆ spaces ...

On cofree S-spaces and cofree S-flows

open access: yesApplied General Topology, 2012
Let S-Tych be the category of Tychonoff S-spaces for a topological monoid S. We study the cofree S-spaces and cofree S-flows over topological spaces and we prove that for any topological space X and a topological monoid S, the function space C(S,X) with ...
