Newton Binomial Formulas in Schubert Calculus
Jorge Cordovez, Letterio Gatto, Taise Santiago
We prove Newton's binomial formulas for Schubert Calculus to determine numbers of base point free linear series on the projective line with prescribed ramification divisor supporte…
Hilbert-Chow morphism for non commutative Hilbert schemes and moduli spaces of linear representations
Federica Galluzzi, Francesco Vaccarino
Let be a commutative ring and let be a commutative algebra. The aim of this paper is to define and discuss some connection morphisms between schemes associated to the r…
On the Gorenstein locus of some punctual Hilbert schemes
Gianfranco Casnati, Roberto Notari
Let be an algebraically closed field and let $\Hilb_{d}^{G}(\p{N})$ be the open locus of the Hilbert scheme $\Hilb_{d}(\p{N})$ corresponding to Gorenstein subschemes. We prove…
The Equations of Singular Loci of Ample Divisors on (Subvarieties of) Abelian Varieties
Luigi Lombardi, Francesco Malaspina
In this paper we consider ideal sheaves associated to the singular loci of a divisor in a linear system of an ample line bundle on a complex abelian variety. We prove an effe…
