Group algebras

open access: yesIndian Journal of Pure and Applied Mathematics, 2012
Let \(KG\) be the group ring of a group \(G\) over a ring \(K\). An element \(\alpha\in KG\) is said to be algebraic over \(K\) if there exists a non-constant polynomial \(f(x)\in K[x]\) such that \(f(\alpha)=0\). In this paper the author makes a survey of the main results in the theory of group rings for algebraic elements which are obtained in recent

Group Structures and Derivations on PMS-algebras [version 1; peer review: 2 approved] [PDF]

open access: yesF1000Research
Background PMS-algebras are a specific algebraic structure that generalizes a propositional algebra called BCK-algebra. This paper delves into the intricate group structure of these algebras and the concept of derivations within this framework.

On ideals in group algebras: An uncertainty principle and the Schur product [PDF]

open access: yesForum mathematicum, 2022
In this paper, we investigate some properties of ideals in group algebras of finite groups over fields. First, we highlight an important link between their dimension, their minimal Hamming distance and the group order. This is a generalized version of an

Non-isomorphic 2-groups with isomorphic modular group algebras [PDF]

open access: yesJournal für die Reine und Angewandte Mathematik, 2021
We provide non-isomorphic finite 2-groups which have isomorphic group algebras over any field of characteristic 2, thus settling the Modular Isomorphism Problem.

(Non)exotic Completions of the Group Algebras of Isotropy Groups [PDF]

open access: yesInternational mathematics research notices, 2020
Motivated by the problem of characterizing KMS states on the reduced C$^*$-algebras of étale groupoids, we show that the reduced norm on these algebras induces a C$^*$-norm on the group algebras of the isotropy groups.

Hecke group algebras as degenerate affine Hecke algebras [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
The Hecke group algebra $\operatorname{H} \mathring{W}$ of a finite Coxeter group $\mathring{W}$, as introduced by the first and last author, is obtained from $\mathring{W}$ by gluing appropriately its $0$-Hecke algebra and its group algebra.

BD algebras and group cohomology

open access: yesComptes Rendus. Mathématique, 2021
BD algebras (Beilinson–Drinfeld algebras) are algebraic structures which are defined similarly to BV algebras (Batalin–Vilkovisky algebras). The equation defining the BD operator has the same structure as the equation for BV algebras, but the BD operator

Biamenability of Banach algebras and its applications [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2023
In this paper, we introduce the concept of biamenability of Banach algebras and we show that despite the apparent similarities between amenability and biamenability of Banach algebras, they lead to very different, and somewhat opposed, theories.

Unit groups of group algebras on certain quasidihedral groups [PDF]

open access: yesSurveys in Mathematics and its Applications, 2022
Let Fq be any finite field of characteristic p>0 having q = pn elements. In this paper, we have obtained the complete structure of unit groups of group algebras Fq[QD2k], for k = 4 and 5, for any prime p>0, where QD2k is quasidihedral group of order 2k.

A New Approach to Braided T-Categories and Generalized Quantum Yang–Baxter Equations

open access: yesMathematics, 2022
We introduce and study a large class of coalgebras (possibly (non)coassociative) with group-algebraic structures Hopf (non)coassociative group-algebras.
