Commuting maps of inflated algebras

Abstract

Commuting maps on a class of algebras called inflated algebras are investigated. In particular, we can prove that every commuting map $θ$ on such an algebra is of the form $θ(x)=c x+μ(x)$, where $c$ belongs to the base field $K$ of characteristic not 2, and $μ$ is a central-valued linear map.
