A numerical property of Hilbert functions and lex segment ideals
Giuseppe Favacchio
We introduce the fractal expansions, sequences of integers associated to a number. We show that these sequences characterize the O-sequences and encode some information on lex segm…
Multiprojective spaces and the arithmetically Cohen-Macaulay property
Giuseppe Favacchio, Juan Migliore
In this paper we study the arithmetically Cohen-Macaulay (ACM) property for sets of points in multiprojective spaces. Most of what is known is for a…
Special arrangements of lines: codimension two ACM varieties in
Giuseppe Favacchio, Elena Guardo, Beatrice Picone
In this paper we investigate special arrangements of lines in multiprojective spaces. In particular, we characterize codimensional two arithmetically Cohen-Macaulay (ACM) varieties…
On the arithmetically Cohen-Macaulay property for sets of points in multiprojective spaces
Giuseppe Favacchio, Elena Guardo, Juan Migliore
Published version: We study the arithmetically Cohen-Macaulay (ACM) property for finite sets of points in multiprojective spaces, especially . A combinatorial char…
