[PDF][PDF] Presentations Of Rings With Non-Trivial Self-Orthogonal Modules
DA Jorgensen, GJ Leuschke… - arXiv preprint arXiv …, 2009 - Citeseer
A result of Foxby, Reiten and Sharp says that a commutative noetherian local ring R admits
a dualizing module if and only if R is Cohen–Macaulay and a homomorphic image of a local …

On the structure of the set of semidualizing complexes
A Gerko - Illinois Journal of Mathematics, 2004 - projecteuclid.org
We study the structure of the set of semidualizing complexes over a local ring. In particular,
we prove that for a pair of semidualizing complexes $ X_1 $ and $ X_2 $ such that $ G_ {X …

Chains of semidualizing modules
E Amanzadeh - Journal of Algebra and Its Applications, 2018 - World Scientific
Let (R, 𝔪, k) be a commutative Noetherian local ring. We study the suitable chains of

HB Foxby - Mathematische Nachrichten, 1975 - Wiley Online Library
Let M be a finitely generated module over a commutative noetherian ring A (with 1). Then M
