Some aspects of dimension theory for topological groups

open access: yesIndagationes Mathematicae, 2018
In this paper, the authors discuss dimension theory in the class of all topological groups. In the first section, they refer to the dawn of dimension theory in topology, in particular, introduce the research activities of Luitzen Egbertus Jan Brouwer (1881--1966) with Pavel Sergeyevich Alexandroff (1896--1982) and Pavel Samuilovich Urysohn (1898--1924).

On exceptional 't Hooft lines in 4D-Chern-Simons theory

open access: yesNuclear Physics B, 2022
We study ‘t Hooft lines and the associated L- operators in topological 4D Chern-Simons theory with gauge symmetry given by the exceptional groups E6 and E7.

Computational Aspects of Group Extensions and Their Applications in Topology [PDF]

open access: yesExperimental Mathematics, 2002
We describe algorithms to determine extensions of infinite polycyclic groups having certain properties. In particular, we are interested in torsion-free extensions and extensions whose Fitting subgroup has a minimal centre. Then we apply these methods in topological applications. We discuss the calculation of Betti numbers for compact manifolds, and we

Charge ambiguity and splitting of monopoles

open access: yesPhysical Review Research, 2022
This paper focuses on topological defects, appearing in mean-field-theory treatments of physical systems such as ultracold atomic gases and gauge field theories.

Topological and Geometrical Properties of k-Symplectic Structures

open access: yesAxioms, 2022
We study new geometrical and topological aspects of polarized k-symplectic manifolds. In addition, we study the De Rham cohomology groups of the k-symplectic group.

Topologies Generated by Two Ideals and the Corresponding j-Approximations Spaces with Applications

open access: yesJournal of Mathematics, 2021
Ideal is a fundamental concept in topological spaces and plays an important role in the study of topological problems. This motivated us to use two ideals to generate different topologies to take the advantage of the two ideals at the same time.

$a\times b=c$ in $2+1$D TQFT [PDF]

open access: yesQuantum, 2021
We study the implications of the anyon fusion equation $a\times b=c$ on global properties of $2+1$D topological quantum field theories (TQFTs). Here $a$ and $b$ are anyons that fuse together to give a unique anyon, $c$.

A study of some aspects of topological groups [PDF]

open access: yesFilomat, 2007
The aim of this paper is to find a generalization of topological groups. The concept arises out of the investigation to obtain a group structure on the set [X,Y], of homotopy classes of maps from a space X to a given space Y for all X which is natural with respect to X. We also study the generalized topological groups.
