Algebraic surfaces as Hadamard products of curves
Dario Antolini, Edoardo Ballico, Alessandro Oneto
We study projective surfaces in which can be written as Hadamard product of two curves. We show that quadratic surfaces which are Hadamard product of two lines are s…
Quantizations of local Calabi-Yau threefolds and their moduli of vector bundles
Edoardo Ballico, Elizabeth Gasparim, Francisco Rubilar +1
We describe the geometry of noncommutative deformations of local Calabi-Yau threefolds, showing that the choice of Poisson structure strongly influences the geometry of the quantum…
Terracini loci and a codimension one Alexander-Hirschowitz theorem
Edoardo Ballico, Maria Chiara Brambilla, Claudio Fontanari
The Terracini locus is the locus of all finite subsets of of cardinality such that , $h^0(\mathcal{I…
On the Hilbert scheme of smooth curves of degree in
Edoardo Ballico, Changho Keem
We denote by the Hilbert scheme of smooth curves, which is the union of components whose general point corresponds to a smooth, irreducible and non-degenerate…
