On Nilpotent Elements and Armendariz Modules

open access: yesMathematics
For a left module MR over a non-commutative ring R, the notion for the class of nilpotent elements (nilR(M)) was first introduced and studied by Sevviiri and Groenewald in 2014 (Commun. Algebra, 42, 571–577).

On linear subspaces of nilpotent elements in a Lie algebra [PDF]

open access: yesLinear Algebra and Its Applications, 1998
Let g be a complex semi-simple Lie algebra. Extending a result of Gerstenhaber on spaces of nilpotent matrices, it is shown that if W ⊂ g is a linear subspace of ad nilpotent elements then dim W ≤ 12 (dim g — rank g).

Unification and equation solving in nilpotent groups and monoids [PDF]

open access: yes, 1991
Unification and equation solving have been considered for groups [44], semigroups [43], abelian groups [39] and abelian semigroups [25], [33], [68], [69]. In this thesis we consider partially commutative groups and monoids. Nilpotency provides us with a

Nilpotent injectors in finite groups [PDF]

open access: yes, 2011
We prove that the odd nilpotent injectors (a certain type of maximal nilpotent subgroup) f a minimal simple group are all conjugate, extending the result from soluble groups. We also prove conjugacy in GU(\_3\)(q) and SU(\_3\)(q).

Engel Conditions for Soluble and Pronilpotent Groups [PDF]

open access: yesAdvances in Group Theory and Applications, 2022
Let G be a finitely generated pronilpotent group in which for any elements x, y ∈ G there are positive integers n = n(x, y) and q = q(x, y) such that [x, n y^q] = 1. We show that G is virtually nilpotent.

On the idempotent and nilpotent sum numbers of matrices over certain indecomposable rings and related concepts

open access: yesМатематичні Студії, 2021
We investigate a few special decompositions in arbitrary rings and matrix rings over indecomposable rings into nilpotent and idempotent elements. Moreover, we also define and study the nilpotent sum trace number of nilpotent matrices over an arbitrary ...

Reflexivity of rings via nilpotent elements [PDF]

open access: yesRevista de la Unión Matemática Argentina, 2020
An ideal $I$ of a ring $R$ is called left N-reflexive if for any $a\in$ nil$(R)$, $b\in R$, being $aRb \subseteq I$ implies $bRa \subseteq I$ where nil$(R)$ is the set of all nilpotent elements of $R$. The ring $R$ is called left N-reflexive if the zero ideal is left N-reflexive.

Enumerating finite class-2-nilpotent groups on 2 generators [PDF]

open access: yes, 2009
We compute the numbers g(n,2,2) of nilpotent groups of order n, of class atmost 2 generated by at most 2 generators, by giving an explicit formula for theDirichlet generating function \sum_{n=1}^\infty g(n,2,2)n^{-s}

Nilpotent subspaces of maximal dimension in semisimple Lie algebras [PDF]

open access: yes, 2006
We show that a linear subspace of a reductive Lie algebra g that consists of nilpotent elements has dimension at most equal to the number of positive roots, and that any nilpotent subspace attaining this upper bound is equal to the nilradical of a Borel ...
