Topological Structures on DMC Spaces † [PDF]

open access: yesEntropy, 2017
Two channels are said to be equivalent if they are degraded from each other. The space of equivalent channels with input alphabet X and output alphabet Y can be naturally endowed with the quotient of the Euclidean topology by the equivalence relation.

The character of free topological groups I

open access: yesApplied General Topology, 2005
A systematic analysis is made of the character of the free and free abelian topological groups on uniform spaces and on topological spaces. In the case of the free abelian topological group on a uniform space, expressions are given for the character in ...

Topological States of Matter [PDF]

open access: yes, 2012
My research program is focused on the study of elastic deformation and topological defects in two materials: graphene and topological insulators. In both systems at low energies the electrons have a nearly linear spectrum, i.e.

p-topological Cauchy completions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
The duality between “regular” and “topological” as convergence space properties extends in a natural way to the more general properties “p-regular” and “p-topological.” Since earlier papers have investigated regular, p-regular, and topological Cauchy ...

Aspects of Topological String Theory [PDF]

open access: yes, 2008
Two aspects of the topological string and its applications are considered in this thesis. Firstly, non-perturbative contributions to the OSV conjecture relating four-dimensional extremal black holes and the closed topological string partition function ...

Spin, Orbital, Weyl and Other Glasses in Topological Superfluids [PDF]

open access: yes, 2018
| openaire: EC/H2020/694248/EU//TOPVACOne of the most spectacular discoveries made in superfluid 3He confined in a nanostructured material like aerogel or nafen was the observation of the destruction of the long-range orientational order by a weak random

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

Bi*-topological space

open access: yesNTU Journal of Pure Sciences
Bi-topological spaces provide a general framework for studying mathematical structures endowed with two distinct topologies, enabling the investigation of concepts that cannot be fully characterized in classical topology.

Nigh-Open Sets in Topological Space

open access: yesInternational Journal of Analysis and Applications, 2023
In this paper, we aim to introduce a new class of open sets namely nigh-open set. Accordingly, we define a topological space called a nigh-topological space. This consequently leads us to outline several new operations in connection with the sets in nigh-
