Jordan-Chevalley decompositions over imperfect fields

arXiv:2604.08740

Abstract

We give a classification of Jordan-Chevalley decompositions of an endomorphism of a finite-dimensional vector space over a not necessarily perfect field, i.e. additive decompositions into commuting semisimple and nilpotent endomorphisms.
