Castelnuovo–Mumford regularity and powers
This note has two goals. The first is to give a short and self contained introduction to the
Castelnuovo–Mumford regularity for standard graded rings R=⊕ i∈ ℕ R i over general base …

[HTML][HTML] A remark on regularity of powers and products of ideals
W Bruns, A Conca - Journal of Pure and Applied Algebra, 2017 - Elsevier
We give a simple proof for the fact that the Castelnuovo–Mumford regularity and related
invariants of products of powers of ideals are asymptotically linear in the exponents …

The (ir) regularity of Tor and Ext
We investigate the asymptotic behavior of Castelnuovo-Mumford regularity of Ext and Tor,
with respect to the homological degree, over complete intersection rings. We derive from a …

Finitely generated saturated multi-Rees algebras
S Das, S Roy - Journal of Algebra, 2024 - Elsevier
We study the question of finite generation of saturated multi-Rees algebras and investigate
the asymptotic behaviour of related length functions. In the setup of excellent local domains …

Powers and products of monomial ideals related to determinantal ideals of maximal minors
A Banerjee, D Ghosh, S Selvaraja - arXiv preprint arXiv:1902.09748, 2019 - arxiv.org
Let $ X $ be an $ m\times n $ matrix of distinct indeterminates over a field $ K $, where $
m\le n $. Set the polynomial ring $ K [X]:= K [X_ {ij}: 1\le i\le m, 1\le j\le n] $. Let $1\le k< l\le n …
