Matrices over Finite Fields of Characteristic 2 as Sums of Diagonalizable and Square-Zero Matrices

Peter Danchev, Esther García, Miguel Gómez Lozano

We investigate the problem asking when any square matrix whose entries lie in a finite field of characteristic 2 is decomposable into the sum of a diagonalizable matrix and a nilpo…

Matrices over finite fields of odd characteristic as sums of diagonalizable and square-zero matrices

Peter Danchev, Esther García, Miguel Gómez Lozano

Let be a finite field of odd characteristic. When , we prove that every matrix admits a decomposition into where is diagonalizable and…

Decompositions of Periodic Matrices into a Sum of Special Matrices

Peter Danchev, Esther García, Miguel Gómez Lozano

We study the problem of when a periodic square matrix of order over an arbitrary field is decomposable into the sum of a square-zero matrix and a torsion matrix, a…
