Classifying group algebras in which the socle of the center is an ideal [PDF]

open access: yesCommunications in Algebra, 2023
Let F be a field. We study the structure of finite groups G for which the socle of the center of the group algebra FG is an ideal in FG. In previous work (Brenner-Külshammer, 2024), we studied which general implications this ring-theoretic property of FG

The socle of the group algebra of a finite p-group [PDF]

open access: yesJournal of Algebra, 2023
Let $G$ be a finite $p$-group, and $\alpha$ an automorphism of the group algebra ${\mathbb F}_pG$. Then $\alpha$ fixes the socle of ${\mathbb F}_pG$ pointwise.

Group algebras in which the socle of the center is an ideal [PDF]

open access: yesAnnals of Representation Theory, 2022
Let $F$ be a field of characteristic $p>0$. We study the structure of the finite groups $G$ for which the socle of the center of $FG$ is an ideal in $FG$ and classify the finite $p$-groups $G$ with this property. Moreover, we give an explicit description

A classification of finite primitive IBIS groups with alternating socle [PDF]

open access: yesJournal of group theroy, 2022
Let 𝐺 be a finite permutation group on Ω. An ordered sequence ( ω 1 , … , ω ℓ ) (\omega_{1},\ldots,\omega_{\ell}) of elements of Ω is an irredundant base for 𝐺 if the pointwise stabilizer is trivial and no point is fixed by the stabilizer of its ...

On construction of k-regular maps to Grassmannians via algebras of socle dimension two [PDF]

open access: yesANNALI SCUOLA NORMALE SUPERIORE - CLASSE DI SCIENZE, 2021
A continuous map $\mathbb{C}^n\to Gr(\tau, N)$ is $k$-regular if the $\tau$-dimensional subspaces corresponding to images of any $k$ distinct points span a $\tau k$-dimensional space. For $\tau = 1$ this essentially recovers the classical notion of a $k$-

Jacobson’s theorem on derivations of primitive rings with nonzero socle: a proof and applications

open access: yesEuropean Journal of Mathematics, 2023
We provide a proof of Jacobson’s theorem on derivations of primitive rings with nonzero socle. Both Jacobson’s theorem and its formulation (in terms of the so-called differential operators on left vector spaces over a division ring) underlie our paper ...

Caractéristiques physico-chimiques des eaux souterraines du socle du bassin versant de Goroubi dans la commune de Torodi /Liptako nigérien

open access: yesInternational Journal of Biological and Chemical Sciences, 2022
La région d’étude est située en zone de socle dans la commune rurale de Torodi, partie sud-ouest du Niger, où l’alimentation en eau des populations est faite à partir des eaux de surfaces et des nappes superficielles.

Socle equivalences of weighted surface algebras [PDF]

open access: yes, 2020
We describe the structure and properties of the finite-dimensional symmetric algebras over an algebraically closed field $K$ which are socle equivalent to the general weighted surface algebras of triangulated surfaces, investigated in Erdmann and ...

The socle tableau as a dual version of the Littlewood–Richardson tableau [PDF]

open access: yesJournal of the London Mathematical Society, 2020
Like the LR‐tableau, a socle tableau is given as a skew diagram with certain entries. Unlike in the LR‐tableau, the entries in the socle tableau are weakly increasing in each row, strictly increasing in each column and satisfy a modified lattice ...

Characterizations of a commutative semisimple modular annihilator Banach algebra through its socle

open access: yes, 2021
Let A be a commutative complex semisimple Banach algebra. In this paper we continue the study of kh(soc(A)). Thus we will give, among other things, some new characterizations of this ideal in terms of the closure, in the spectral radius norm, of the ...
