On the Nilpotent Commutator of a Nilpotent Matrix [PDF]

Linear and Multilinear Algebra, 2012
We study the structure of the nilpotent commutator $\nb$ of a nilpotent matrix $B$. We show that $\nb$ intersects all nilpotent orbits for conjugation if and only if $B$ is a square--zero matrix. We describe nonempty intersections of $\nb$ with nilpotent orbits in the case the $n \times n$ matrix $B$ has rank $n-2$.

The Upper Bound for the Index of Nilpotency for a Matrix Commuting With a Given Nilpotent Matrix

Linear and Multilinear Algebra, 2008
We study the set $\partition{\nb}$ of all possible Jordan canonical forms of nilpotent matrices commuting with a given nilpotent matrix $B$. We describe $\partition{\nb}$ in the special case when $B$ has only one Jordan block. In the general case, we find the maximal possible index of nilpotency in the set of all nilpotent matrices commuting with a ...

Commuting Solutions of a Quadratic Matrix Equation for Nilpotent Matrices

Algebra Colloquium, 2018
We solve the quadratic matrix equation AXA = XAX with a given nilpotent matrix A, to find all commuting solutions. We first provide a key lemma, and consider the special case that A has only one Jordan block to motivate the idea for the general case ...

Counting Symmetric Nilpotent Matrices [PDF]

Electronic Journal of Combinatorics, 2014
We determine the number of nilpotent matrices of order n over Fq that are self-adjoint for a given nondegenerate symmetric bilinear form, and in particular find the number of symmetric nilpotent matrices.

On T-nilpotence of a matrix set

Buletinul Academiei de Ştiinţe a Republicii Moldova. Matematica, 2023
Let R be a ring and I be an arbitrary right T-nilpotent subset of R. In the paper it is proved that in this case the set of all n×n-matrices with entries in I is a right T-nilpotent subset of the ring of n×n-matrices with entries in R, where n 2 N.
