Regular Hom-Lie structures on incidence algebras

Érica Z. Fornaroli, Mykola Khrypchenko, Ednei A. Santulo

We fully characterize regular Hom-Lie structures on the incidence algebra $I (X, K)$ of a finite connected poset $X$ over a field $K$ . We prove that such a structure is the sum of a…

Commutativity preservers of incidence algebras

Érica Z. Fornaroli, Mykola Khrypchenko, Ednei A. Santulo

Let $I (X, K)$ be the incidence algebra of a finite connected poset $X$ over a field $K$ and $D (X, K)$ its subalgebra consisting of diagonal elements. We describe the bijective linear…
