Résumé
Abstract

Soient $D \subseteq E$ une extension dʼanneaux commutatifs unitaires, I un idéal non nul et propre de D et Γ un monoïde commutatif simplifiable sans torsion non trivial tel que $Γ \cap - Γ = {0}$ et $Γ^{⁎} = Γ ∖ {0}$ . Soient $E [Γ]$ lʼanneau semi-groupe de Γ sur E, $D + E [Γ^{⁎}] = {f \in E [Γ] | f (0) \in D}$ et $D + I [Γ^{⁎}] = {f \in D [Γ] |$ les coefficients des termes non-constants de f appartiennent à I}. Dans cet article, nous donnons certaines conditions pour que les anneaux (resp., domaines) $D + E [Γ^{⁎}]$ et $D + I [Γ^{⁎}]$ soient Noethériens (resp., satisfassent la condition de chaîne ascendante sur les idéaux principaux).

Let $D \subseteq E$ denote an extension of commutative rings with identity, I be a nonzero proper ideal of D, Γ mean a nonzero torsion-free additive grading monoid with $Γ \cap - Γ = {0}$ and $Γ^{⁎} = Γ ∖ {0}$ . Let $E [Γ]$ be the semigroup ring of Γ over E, $D + E [Γ^{⁎}] = {f \in E [Γ] | f (0) \in D}$ and $D + I [Γ^{⁎}] = {f \in D [Γ] |$ the coefficients of nonconstant terms of f belong to I}. In this paper, we give some conditions for the rings (resp., domains) $D + E [Γ^{⁎}]$ and $D + I [Γ^{⁎}]$ to be Noetherian (resp., to satisfy the ascending chain condition on principal ideals).
