On the Hadamard product of degenerate subvarieties
G. Calussi, E. Carlini, G. Fatabbi +1
We consider generic degenerate subvarieties . We determine an integer , depending on the varieties, and for we compute dimension and degree for…
On Hadamard products of linear varieties
C. Bocci, G. Calussi, G. Fatabbi +1
In this paper we address the Hadamard product of linear varieties not necessarily in general position. In we obtain a complete description of the possible outcomes.…
Symbolic powers of codimension two Cohen-Macaulay ideals
Susan Cooper, Giuliana Fatabbi, Elena Guardo +6
Let be the saturated homogeneous ideal defining a codimension two arithmetically Cohen-Macaulay scheme , and let denote its -th symbo…
Inclics, galaxies, star configurations and Waldschmidt constants
Giuliana Fatabbi, Brian Harbourne, Anna Lorenzini
This paper introduces complexes of linear varieties, called inclics (for INductively Constructible LInear ComplexeS). As examples, we study galaxies (these are constructed starting…
Resolutions of ideals of fat points with support in a hyperplane
Giuliana Fatabbi, Brian Harbourne, Anna Lorenzini
Our results concern minimal graded free resolutions of fat point ideals for points in a hyperplane. Suppose, for example, that I(m,d) is the ideal defining r given points of multip…
Blowing up determinantal cerves and varieties of codim 2
A. Gimigliano, A. Lorenzini
We study the blow-ups X of P3 along a proj. normal curve C. We look for very ample divisor classes on X of low degree, and we study the ideal of the embedding of X. Some result is…
