On Rees algebras of linearly presented ideals and modules

Alessandra Costantini, Edward F. Price, Matthew Weaver

Let $I$ be a perfect ideal of height two in $R = k [x_{1}, \dots, x_{d}]$ and let $φ$ denote its Hilbert-Burch matrix. When $φ$ has linear entries, the algebraic structure of the Rees al…

The combinatorial structure of symmetric strongly shifted ideals

Alessandra Costantini, Alexandra Seceleanu

Symmetric strongly shifted ideals are a class of monomial ideals which come equipped with an action of the symmetric group and are analogous to the well-studied class of strongly s…
