In 1995, Faith and Menal have established the V-ring theorem which gives a characterization of a V-ring. In this paper, we generalize this theorem to V-modules and consider some applications for Noetherian self-cogenerators.
This is an exposition of Goldie’s theorem with a section on Ore localization and with an application to defining ranks for finitely generated modules over non–commutative noetherian rings.
In this note, it is proved that over a commutative noetherian henselian non-Gorenstein local ring there are infinitely many isomorphism classes of indecomposable totally reflexive modules, if there is a nonfree cyclic totally reflexive module.
we investigate buchbaum and eisenbud's construction of the second symmetric power $s_r(x)$ of a chain complex $x$ of modules over a commutative ring $r$. we state and prove a number of results from the folklore of the subject for which we know of no good direct references. we also provide several explicit computations and examples. we use this construction to prove the following ...
Skew polynomial rings have invited attention of mathematicians and various properties of these rings have been discussed. The nature of ideals (in particular prime ideals, minimal prime ideals, associated prime ideals), primary decomposition and Krull dimension have been investigated in certain cases. In this article, we introduce a notion of primary decomposition of a noncommutative ring. We s...
Let A be a noetherian local commutative ring and let M be a suitable complex of A-modules. This paper proves that M is a dualizing complex for A if and only if the trivial extension A ⋉M is a Gorenstein Differential Graded Algebra. As a corollary follows that A has a dualizing complex if and only if it is a quotient of a Gorenstein local Differential Graded Algebra. Let A be a noetherian local ...
It is shown that if $M$ is an Artinian module over a ring $R$, then $M$ has Noetherian dimension $alpha $, where $alpha $ is a countable ordinal number, if and only if $omega ^{alpha }+2leq it{l}(M)leq omega ^{alpha +1}$, where $ it{l}(M)$ is the length of $M$, $i.e.,$ the least ordinal number such that the interval $[0, it{l}(M))$ cannot be embedded in the lattice of all su...
In this paper, we describe all automorphism-liftable torsion modules over non-primitive hereditary Noetherian prime rings. We also study non-torsion not necessarily commutative Dedekind
