Regularity of normal Rees algebras of edge ideals of graphs

Cao Huy Linh, Quang Hoa Tran, Thanh Vu

We classify all graphs for which the Rees algebras of their edge ideals are normal and have regularity equal to their matching numbers.

Boundedness of Cohomology

Markus Brodmann, Maryam Jahangiri, Cao Huy Linh

Let $d \in N$ and let $\D^d$ denote the class of all pairs $(R, M)$ in which $R = ⨁_{n \in N_{0}} R_{n}$ is a Noetherian homogeneous ring with Artinian base ring $R_{0}$ and suc…

Castelnuovo-Mumford regularity of deficiency modules

Markus Brodmann, Maryam Jahangiri, Cao Huy Linh

Let $d \in N$ and let $M$ be a finitely generated graded module of dimension $\leq d$ over a Noetherian homogeneous ring $R$ with local Artinian base ring $R_{0}$ . Let $\beg(M)$, $\…

Uniform bounds in generalized Cohen-Macaulay rings

Cao Huy Linh, Ngo Viet Trung

We establish a uniform bound for the Castelnuovo-Mumford regularity of associated graded rings of parameter ideals in a generalized Cohen-Macaulay ring. As consequences, we obtain…
