Rees algebras of unit interval determinantal facet ideals

open access: yes
Using SAGBI basis techniques, we find Gröbner bases for the presentation ideals of the Rees algebras and special fiber rings of unit interval determinantal facet ideals.

Rees Algebras of Modules

Proceedings of the London Mathematical Society, 2003
Summary: We study Rees algebras of modules within a fairly general framework. We introduce an approach through the notion of Bourbaki ideals that allows the use of deformation theory. One can talk about the (essentially unique) generic Bourbaki ideal \(I(E)\) of a module \(E\) which, in many situations, allows one to reduce the nature of the Rees ...

On quotients of Rees algebras

open access: yesJournal of Pure and Applied Algebra, 2023
Following [\textit{V. Barucci} et al., Commun. Algebra 43, No. 1, 130--142 (2015; Zbl 1327.13087); Ark. Mat. 54, No. 2, 321--338 (2016; Zbl 1372.13017)] the authors of the paper, investigate on a family of quadratic quotients of Rees algebras over a commutative ring.

Grothendieck–Serre formula and bigraded Cohen–Macaulay Rees algebras [PDF]

open access: yesJournal of Algebra, 2002
The Grothendieck–Serre formula for the difference between the Hilbert function and Hilbert polynomial of a graded algebra is generalized for bigraded standard algebras.
