Sharp bounds on Castelnuovo-Mumford regularity [PDF]

open access: yesTransactions of the American Mathematical Society, 1999
The Castelnuovo-Mumford regularity of a subscheme \(X \subseteq \mathbb{P}^n_K\) is an important invariant of this embedding. If \(K\) is algebraically closed of characteristic zero, and \(X\) is nondegenerate, irreducible and \(k\)-Buchsbaum, it was shown by \textit{U. Nagel} and \textit{P. Schenzel} [Nagoya Math. J. 152, 153-174 (1998; Zbl 0945.13008)

Castelnuovo–Mumford regularity of canonical and deficiency modules

open access: yesJournal of Algebra, 2006
We give two kinds of bounds for the Castelnuovo-Mumford regularity of the canonical module and the deficiency modules of a ring, respectively in terms of the homological degree and the Castelnuovo-Mumford regularity of the original ring.

Castelnuovo-Mumford Regularity and Edge Ideals [PDF]

open access: yes, 2017
In this dissertation we study the homological algebra of the monomial ideals with a special emphasis on the topics of the Castenuovo-Mumford regularity and the powers of edge ideals of finite simple graphs. The main problem of this dissertation is to find optimal bounds for the regularity of powers of edge ideals.

Castelnuovo-Mumford regularity and cohomological dimension

open access: yes, 2013
Let $R=\oplus_{i\in \N_0}R_n$ be a standard graded ring, $R_+ :=\oplus_{i\in \N}R_n$ be the irrelevant ideal of $R$ and $\fa_0$ be an ideal of $R_0$. In this paper, as a generalization of the concept of Castelnouvo-Mumford regularity $\reg(M)$ of a finitely generated graded $R$-module $M$, we define the regularity of $M$ with respect to $\fa_0+ R_ ...

Bounds for the Castelnuovo-Mumford regularity

open access: yes, 2008
Bayer et Stillman ont montré que si R est un anneau de polynômes sur un corps k et I un idéal homogène de R, alors la régularité de I est égal au maximum des degrés des générateurs de son idéal initial générique pour l'ordre lexicographique inverse.
