On Finite Nilpotent Matrix Groups over Integral Domains [PDF]

open access: yesISRN Algebra, 2013
We consider finite nilpotent groups of matrices over commutative rings. A general result concerning the diagonalization of matrix groups in the terms of simple conditions for matrix entries is proven. We also give some arithmetic applications for representations over Dedekind rings.

NILPOTENTS ZERO DIVISORS OF A MULTIDIMENSIONAL MATRIX

open access: yes, 2022
In this article, the necessary conditions for nilpotency of matrices of three and higher dimensions are studied. In addition, its application to quadratic stochastic operators is presented.

Finite Matrix Groups over Nilpotent Group Rings

open access: yesJournal of Algebra, 1996
Let \(\mathbb{Z} H\) be the integral group ring of a group \(H\). The authors study the group \(\text{SGL}_n(\mathbb{Z} H)\) of matrices of augmentation one over the group ring \(\mathbb{Z} H\), and relate the torsion of \(\text{SGL}_n(\mathbb{Z} H)\) to the torsion of \(H\).

On n-quasi- [m,C] $[m,C]$-isometric operators

open access: yesJournal of Inequalities and Applications, 2019
For positive integers m and n, an operator T∈B(H) $T \in B ( H )$ is said to be an n-quasi- [m,C] $[m,C]$-isometric operator if there exists some conjugation C such that T∗n(∑j=0m(−1)j(mj)CTm−jC.Tm−j)Tn=0 . In this paper, some basic structural properties

Quick design of feasible tensor networks for constrained combinatorial optimization [PDF]

open access: yesQuantum
Quantum computers are expected to enable fast solving of large-scale combinatorial optimization problems. However, their limitations in fidelity and the number of qubits prevent them from handling real-world problems.

Subspaces Fixed by a Nilpotent Matrix

open access: yes, 2023
The linear spaces that are fixed by a given nilpotent $n \times n$ matrix form a subvariety of the Grassmannian. We classify these varieties for small $n$.

Potentially nilpotent patterns and the Nilpotent-Jacobian method [PDF]

open access: yes, 2012
A nonzero pattern is a matrix with entries in {0,∗}. A pattern is potentially nilpotent if there is some nilpotent real matrix with nonzero entries in precisely the entries indicated by the pattern. We develop ways to construct some potentially nilpotent

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).

Algorithm to compute minimal matrix representation of nilpotent lie algebras

open access: yesInternational Journal of Computer Mathematics, 2019
As it is well-known there exist matrix representations of any given finite-dimensional complex Lie algebra. More concretely, such representations can be obtained by means of an isomorphic matrix Lie algebra consisting of upper-triangular square matrices.
