An intrinsic definition of the Rees algebra of a module

open access: yes, 2017
This paper concerns a generalization of the Rees algebra of ideals due to Eisenbud, Huneke and Ulrich that works for any finitely generated module over a noetherian ring. Their definition is in terms of maps to free modules.

A note on the Rees algebra of a bipartite graph

open access: yes, 2005
Let R=K[x1,…,xn] be a polynomial ring over a field K and let I be an ideal of R generated by a set xα1,…,xαq of square-free monomials of degree two such that the graph G defined by those monomials is bipartite.

Rees Algebras of F-regular Type

open access: yesJournal of Algebra, 2002
A reduced ring \(R\) of characteristic \(p> 0\) is said to be F-regular if the map \(R\to R^{1/p}\) is module-finite and for every \(c\in R\) not in any minimal prime of \(R\), there exists a power \(q= p^e\) such that the \(R\)-linear inclusion \(c^{1/q}R\to R^{1/q}\) splits.

A construction of Prüfer rings involving quotients of Rees algebras

open access: yes, 2017
A family of quotients of a Rees algebra associated to a ring with respect to a fixed ideal was recently introduced by Barucci, D’Anna and Strazzanti. In this paper, we will classify rings of this family that satisfy certain Prüfer-like properties and ...

Links of Prime Ideals and Their Rees Algebras

open access: yesJournal of Algebra, 1995
In a previous paper we exhibited the somewhat surprising property that most direct links of prime ideals in Gorenstein rings are equimultiple ideals with reduction number $1$. This led to the construction of large families of Cohen--Macaulay Rees algebras. The first goal of this paper is to extend this result to arbitrary Cohen--Macaulay rings.

Symbolic Rees algebra and polynomials

open access: yes, 2009
Let K be a field and P be the kernel of the homomorphism from K[[x, y, z]] to K[[t]] defined by {x -\u3e tn, y -\u3e tm, z -\u3e tl }. One wishes to know whether the Symbolic Rees algebra of P, [special characters omitted] is Noetherian.

Newton-Okounkov body, Rees algebra, and analytic spread of graded families of monomial ideals

open access: yes, 2023
Let $\mathcal{I} = \{I_k\}_{k \in \mathbb{N}}$ be a graded family of monomial ideal. We use the Newton-Okounkov body of $\mathcal{I}$ to: (a) give a characterization for the Noetherian property of the Rees algebra of the family; and (b) present a ...

Rees cones and monomial rings of matroids

open access: yes, 2008
Using linear algebra methods we study certain algebraic properties of monomial rings and matroids. Let I be a monomial ideal in a polynomial ring over an arbitrary field.
