Configurations of points in projective space and their projections
Luca Chiantini, Łucja Farnik, Giuseppe Favacchio +4
We call a set of points an -geproci set (for GEneral PROjection is a Complete Intersection) if its projection from a general point …
Rational normal curves and Hadamard products
Enrico Carlini, Maria Virginia Catalisano, Giuseppe Favacchio +1
Given general hyperplanes in a star configuration of points is the set of all the -wise intersection of them. We introduce {\it contact star configurations}…
Steiner Configurations ideals: containment and colouring
Edoardo Ballico, Giuseppe Favacchio, Elena Guardo +2
Given a homogeneous ideal , the Containment problem studies the relation between symbolic and regular powers of , that is, it asks for which pair $…
The ACM property for unions of lines in
Giuseppe Favacchio, Juan Migliore
This paper examines the Arithmetically Cohen-Macaulay (ACM) property for certain codimension 2 varieties in called sets of lines in $\mathbb P^1\tim…
Steiner systems and configurations of points
Edoardo Ballico, Giuseppe Favacchio, Elena Guardo +1
The aim of this paper is to make a connection between design theory and algebraic geometry/commutative algebra. In particular, given any Steiner System we associate two…
Regularity and h-polynomials of toric ideals of graphs
Giuseppe Favacchio, Graham Keiper, Adam Van Tuyl
For all integers , we show that there exists a finite simple graph with toric ideal such that has (Castelnuovo-Mumford) regula…
