Lie Nilpotency Indices of Modular Group Algebras [PDF]

open access: yesAlgebra Colloquium, 2010
Let K be a field of positive characteristic p and KG the group algebra of a group G. It is known that if KG is Lie nilpotent, then its upper (or lower) Lie nilpotency index is at most |G′| + 1, where |G′| is the order of the commutator subgroup. The class of groups G for which these indices are maximal or almost maximal has already been determined ...

Laplacian solitons on nilpotent Lie groups [PDF]

open access: yes, 2016
We investigate the existence of closed $G_2$-structures which are solitons for the Laplacian flow on nilpotent Lie groups. We obtain that seven of the twelve Lie algebras admitting a closed $G_2$-structure do admit a Laplacian soliton.

A Primer on Carnot Groups: Homogenous Groups, Carnot-Carathéodory Spaces, and Regularity of Their Isometries

open access: yesAnalysis and Geometry in Metric Spaces, 2018
Carnot groups are distinguished spaces that are rich of structure: they are those Lie groups equipped with a path distance that is invariant by left-translations of the group and admit automorphisms that are dilations with respect to the distance.

An application of Lie groupoids to a rigidity problem of 2-step nilmanifolds [PDF]

open access: yesMathematica Bohemica, 2019
We study a problem of isometric compact 2-step nilmanifolds $M/\Gamma$ using some information on their geodesic flows, where $M$ is a simply connected 2-step nilpotent Lie group with a left invariant metric and $\Gamma$ is a cocompact discrete subgroup ...

On the derivations of cyclic Leibniz algebras

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2022
Let $L$ be an algebra over a field $F$. Then $L$ is called a left Leibniz algebra, if its multiplication operation $[-,-]$ additionally satisfies the so-called left Leibniz identity: $[[a,b],c]=[a,[b,c]]-[b,[a,c]]$ for all elements $a,b,c\in L$. A linear

Hypercomplex eight-dimensional nilpotent Lie groups

open access: yesJournal of Pure and Applied Algebra, 2003
A general classification of nilpotent Lie algebras exists only in dimension \(\leq 7\). In this paper, the authors obtain a description of all \(8\)--dimensional nilpotent Lie algebras with hypercomplex structures. They prove that the existence of a hypercomplex structure implies strong restrictions on the Lie algebra.

Discrete Cocompact Subgroups of the Five-Dimensional Connected and Simply Connected Nilpotent Lie Groups

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
The discrete cocompact subgroups of the five-dimensional connected, simply connected nilpotent Lie groups are determined up to isomorphism. Moreover, we prove if G = N × A is a connected, simply connected, nilpotent Lie group with an Abelian factor A ...

Quiver theories and formulae for Slodowy slices of classical algebras

open access: yesNuclear Physics B, 2019
We utilise SUSY quiver gauge theories to compute properties of Slodowy slices; these are spaces transverse to the nilpotent orbits of a Lie algebra g.

Generalized Reduced Mal'tsev Problem on Commutative Subalgebras of $E_6$ Type Chevalley Algebras over a Field

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2019
In 1905 I.~Shur pointed out the largest dimension of commutative subgroups in the groups $SL(n,\mathbb{C})$ and proved that for $n>3$ such the subgroups are automorphic to each other.
