Covers and Envelopes by V-Gorenstein Modules

EE Enochs, OMG Jenda… - Communications in …, 2005 - Taylor & Francis
In this article, we study V-Gorenstein modules relatives to a dualizing module (Enochs et
al.,). These modules constitute a generalization of the well-known Gorenstein modules and …

Gorenstein injective envelopes and covers over two sided noetherian rings

A Iacob - Communications in Algebra, 2017 - Taylor & Francis
We prove that the class of Gorenstein injective modules is both enveloping and covering
over a two sided noetherian ring such that the character modules of Gorenstein injective …

Gorenstein flat covers of modules over Gorenstein rings

E Enochs, J Xu - Journal of Algebra, 1996 - Elsevier
A left and right Noetherian ringRis called Gorenstein if bothRRandRRhave finite injective
dimensions. These rings were studied by Bass for the commutative case and Iwanaga for …

Gorenstein dimensions in trivial ring extensions

N Mahdou, K Ouarghi - Commutative Algebra and its Applications, 2009 - degruyter.com
In this paper, we show that the Gorenstein global dimension of trivial ring extensions is often
infinite. Also we study the transfer of Gorenstein properties between a ring and its trivial ring …

𝑛-Gorenstein rings

HB Foxby - Proceedings of the American Mathematical Society, 1974 - ams.org
The object of this note is to study commutative noetherian n-Gorenstein rings. The first result
is: if each module satisfying Samuel's conditions $({{\text {a}} _i}) $ for some $ i\leqq n $ is an …

Gorenstein projective and flat complexes over noetherian rings

E Enochs, S Estrada, A Iacob - Mathematische Nachrichten, 2012 - Wiley Online Library
We give sufficient conditions on a class of R‐modules article amssymb empty C in order for
the class of complexes of article amssymb empty C‐modules, article amssymb empty dwC …

Relative Gorenstein dimensions

D Bennis, JR García Rozas, L Oyonarte - Mediterranean Journal of …, 2016 - Springer
In the last years (Gorenstein) homological dimensions relative to a semidualizing module C
have been subject of several works as interesting extensions of (Gorenstein) homological …

Dualizing modules and n-perfect rings

EE Enochs, OMG Jenda… - Proceedings of the …, 2005 - cambridge.org
In this article we extend the results about Gorenstein modules and Foxby duality to a non-
commutative setting. This is done in § 3 of the paper, where we characterize the Auslander …

A characterization of Gorenstein projective modules

J Wang, L Liang - Communications in Algebra, 2016 - Taylor & Francis
In this article, we give a new characterization of Gorenstein projective modules. As
applications of our result, we prove that a strongly Gorenstein projective module of …

Gorenstein injective and projective complexes

EE Enochs, JR Garcí Rozas - Communications in Algebra, 1998 - Taylor & Francis
In this article we extend the notion of Gorenstein injective and projective modules to that of
complexes and characterize such complexes. We prove that over an n-Gorenstein ring every …
