Anti-isomorphisms and involutions on the idealization of the incidence space over the finitary incidence algebra

Érica Zancanella Fornaroli, Roger Emanuel Moraes Pezzott

Let $K$ be a field and $X$ a partially ordered set (poset). Let $FI(X,K)$ and $I(X,K)$ be the finitary incidence algebra and the incidence space of $X$ over $K$, respectively, and…
