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] Webfor any prime ideal [] in [] that contracts to .This can be shown within basic ring theory (cf.

WebThere are several arguments showing that all ideals in a local Artinian Gorenstein ring are trace ideals: Given an ideal I in R, one such argument considers the exact sequence 0 → I → R → R / I → 0. Applying Hom R ( _, R) yields the top exact sequence below where Ext R 1 ( R / I, R) = 0 because R is self-injective.

The Wedderburn–Artin theorem implies that every simple ring that is finite-dimensional over a division ring is isomorphic to an n-by-n matrix ring over a division ring D, where both n and D are uniquely determined. This is Joseph Wedderburn's original result. Emil Artin later generalized it to the case of left or right Artinian rings. In particular, if is an algebraically closed field, then the matrix ring having entries from is the only finite dimensional Artinian simple algebra over . Webof simple Artinian rings. After everything is said and done, we will explore concrete examples on how some semi-simple Artinian rings break down. Maschke’s Theorem reveals how one can easily create semi-simple Artinian rings.
