Ascent and descent of Artinian module structures under flat base changes

TDM Chau, LT Nhan - Communications in Algebra, 2024 - Taylor & Francis
Abstract Let φ: R→ S be a flat local homomorphism between commutative Noetherian local
rings. In this paper, the ascent and descent of Artinian module structures between R and S …

Homology with the theme of Matlis

M Asgharzadeh, E Mahdavi - arXiv preprint arXiv:2212.10332, 2022 - arxiv.org
Matlis proved a lot of homological properties of the fraction field of an integral domain. In this
paper, we simplify and extend some of them from 1-dimensional (resp. rank one) cases to …

Ascent properties for pairs of modules

S Sather-Wagstaff - Archiv der Mathematik, 2014 - Springer
Given a flat local ring homomorphism R → SR→ S and two finitely generated R-modules M
and N, we describe conditions under which the modules\rm Tor^ R _ i (M, N) Tor i R (M, N) …

In the oldest sense, arithmetic is the study of operations on integers: addition, subtraction,
multiplication, and (when defined) division. A somewhat more modern perspective is that …

NAK for Ext, ascent of module structures, and the blindness of extended modules

BJ Anderson - 2012 - search.proquest.com
This dissertation investigates the interplay between properties of Ext modules and ascent of
module structures along ring homomorphisms. First, we consider a flat local ring …
