Jordan Isomorphisms of the Finitary Incidence Ring of a Partially Ordered Category

Rosali Brusamarello, Érica Z. Fornaroli, Mykola Khrypchenko

Let $C$ be a pocategory, $F I (C)$ the finitary incidence ring of $C$ and $φ$ a Jordan isomorphism of $F I (C)$ onto an associative ring $A$ . We…

Jordan Isomorphisms of Finitary Incidence Algebras

Rosali Brusamarello, Érica Z. Fornaroli, Mykola Khrypchenko

Let $X$ be a partially ordered set, $R$ a commutative $2$ -torsionfree unital ring and $F I (X, R)$ the finitary incidence algebra of $X$ over $R$ . In this note we prove that each $R$ -…
