Decomposition of every square matrix over an algebraically closed field or over a finite field into a sum of a potent matrix and a nilpotent matrix of order 2 is considered. This can be related to our recent paper, published in Linear Multilinear Algebra (2022). The question of when each square matrix over an infinite field can be decomposed into a periodic matrix and a nilpotent matrix of order 2 is also completely considered.
Keywords: field.
Mots-clés : nilpotent matrix, potent matrix, Jordan normal form, rational form
