Skew derivations of incidence algebras

Érica Z. Fornaroli, Mykola Khrypchenko

In the first part of the paper we describe $φ$ -derivations of the incidence algebra $I (X, K)$ of a locally finite poset $X$ over a field $K$ , where $φ$ is an arbitrary automorphism…

Involutions of the second kind on finitary incidence algebras

Érica Zancanella Fornaroli

Let $K$ be a field and $X$ a connected partially ordered set. In the first part of this paper, we show that the finitary incidence algebra $F I (X, K)$ of $X$ over $K$ has an involuti…
