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

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.

The topology of spaces of polygons [PDF]

open access: yesTransactions of the American Mathematical Society, 2012
Let E d ( ℓ ) E_{d}(\ell ) denote the space of all closed n n -gons in R d \mathbb {R}^{d} (where d ≥ 2 d\ge 2 ) with sides of length

ON METACOMPACTNESS IN TOPOLOGICAL SPACES

open access: yesINTERNATIONAL JOURNAL OF MATHEMATICS AND COMPUTER RESEARCH, 2023
In this work, we intend to study metacompact spaces and locally metacompact spaces,and study their properties and their relations with order topological spaces.Several examples are discussed and many wellknown theorems are generalized concerning metacompact [7, 2, 8, 3, 4, 56].

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.

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

open access: yes, 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

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.

Topological spaces of persistence modules and their properties [PDF]

open access: yesJournal of Applied and Computational Topology, 2018
Persistence modules are a central algebraic object arising in topological data analysis. The notion of interleaving provides a natural way to measure distances between persistence modules.

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 ...
