Sally modules and associated graded rings

Alberto Corso, Claudia Polini, Maria Vaz Pinto

We study the depth properties of the associated graded ring of an m-primary ideal I in terms of numerical data attached to the ideal I. We also find bounds on the Hilbert coefficie…

A generalized Dedekind-Mertens lemma and its converse

Alberto Corso, William Heinzer, Craig Huneke

We study content ideals of polynomials and their behavior under multiplication. We give a generalization of the Lemma of Dedekind-Mertens and prove the converse under suitable dime…

Core and residual intersections of ideals

Alberto Corso, Claudia Polini, Bernd Ulrich

D. Rees and J. Sally defined the core of an -ideal as the intersection of all minimal reductions of . However, it is not easy to give an explicit characterization o…

Andre-Quillen homology of algebra retracts

L. L. Avramov, S. Iyengar

Given a homomorphism of commutative noetherian rings , Daniel Quillen conjectured in 1970 that if the Andre-Quillen homology functors vanish for all $n \gg…

Vanishing of cohomology over Gorenstein rings of small codimension

Liana M Sega

We prove that if M, N are finite modules over a Gorenstein local ring R of codimension at most 4, then the vanishing of Ext^n_R(M,N) for n\gg 0 is equivalent to the vanishing of Ex…

What is the Rees Algebra of a Module?

David Eisenbud, Craig Huneke, Bernd Ulrich

In this paper we show that the Rees algebra can be made into a functor on modules over a ring in a way that extends its classical definition for ideals. The Rees algebra of a modul…
