A-graded methods for monomial ideals
Christine Berkesch, Laura Felicia Matusevich
We use \ZZ^d-gradings to study d-dimensional monomial ideals. The Koszul functor is employed to interpret the quasidegrees of local cohomology in terms of the geometry of distracti…

Laura Felicia Matusevich
We show that A-hypergeometric systems and Horn hypergeometric systems are Weyl closed for very generic parameters.
