Artinian ring
Web1 ago 2024 · As an abelian group (that is, as a Z -module ), Z ( p∞) is Artinian but not Noetherian. [3] It can thus be used as a counterexample against the idea that every Artinian module is Noetherian (whereas every Artinian ring is Noetherian). The endomorphism ring of Z ( p∞) is isomorphic to the ring of p -adic integers Zp. [4] Web24 ott 2024 · Commutative Artinian rings A is Artinian.

In mathematics, specifically abstract algebra, an Artinian ring (sometimes Artin ring) is a ring that satisfies the descending chain condition on (one-sided) ideals; that is, there is no infinite descending sequence of ideals. Artinian rings are named after Emil Artin, who first discovered that the descending chain … Visualizza altro Let M be a left module over a left Artinian ring. Then the following are equivalent (Hopkins' theorem): (i) M is finitely generated, (ii) M has finite length (i.e., has composition series), (iii) M is Noetherian, (iv) M is Artinian.

WebA ring is left (right) serial if it is a direct sum of uniserial left (right) modules. It was shown in [5] that an artinian ring R is right serial if and only if every left indecomposable injective Zv-module is uniserial, provided R is commutative modulo its radical. Hill [5] asked if this result can be extended to arbitrary artinian rings.
Web8 gen 2015 · A ring is (left) artinian if it is artinian as a module over itself. Again we have the following basic property. Theorem. If M is artinian, so is any submodule and quotient module of M. Conversely, if N ⊆ M is such that N and M/N are artinian, then so is M. Corollary. If M, N are artinian, so is their direct sum M ⊕ N.

WebA ring is Artinian if and only if it is Noetherian and its Krull dimension is ≤0. An integral extension of a ring has the same dimension as the ring does. Let R be an algebra over a field k that is an integral domain. Then the Krull dimension of R is less than or equal to the transcendence degree of the field of fractions of R over k. [7]
