Algebraic invariants of the special fiber ring of ladder determinantal modules

Alessandra Costantini, Louiza Fouli, Kriti Goel +4

We provide explicit formulas for key invariants of special fiber rings of ladder determinantal modules, that is, modules that are direct sums of ideals of maximal minors of a ladde…

On Rees algebras of ideals and modules with weak residual conditions

Alessandra Costantini, Edward F. Price, Matthew Weaver

Let $E$ be a module of projective dimension one over $R = k [x_{1}, \dots, x_{d}]$ . If $E$ is presented by a matrix $I ¨ $ with linear entries and the number of generators of $E$ is bounded…
