RT journal article T1 On the quotient of affine semigroups by a positive integer A1 García García, Juan Ignacio A1 Tapia Ramos, Raquel A1 Vigneron Tenorio, Alberto A2 Matemáticas K1 Affine semigroup K1 Arithmetic variety K1 C-semigroup K1 Frobenius element K1 Irreducibility K1 Quotient by a positive integer K1 Rooted tree AB This work delves into the quotient of an affine semigroup by a positive integer, exploring its intricate properties and broader implications. We unveil an associated tree that serves as a valuable tool for further analysis. Moreover, we successfully generalize several key irreducibility results, extending their applicability to the more general class of C-semigroup quotients. To shed light on these concepts, we introduce the novel notion of an arithmetic variety of affine semigroups, accompanied by illuminating examples that showcase its power.
