Enumerating finite O-sequences: sub-Fibonacci behavior and growth estimates

Francesca Cioffi, Margherita Guida, Enrica Pirozzi

Let $O_{d}$ denote the number of finite $O$ -sequences of multiplicity $d$ , namely the Hilbert functions of standard graded Artinian quotients of polynomial rings over a field. Starti…

Counting finite $O$ -sequences of a given multiplicity

Francesca Cioffi, Margherita Guida

We study the number $O_{d}$ of finite $O$ -sequences of a given multiplicity $d$ , with particular attention to the computation of $O_{d}$ . We show that the sequence $(O_{d})_{d}$ is sub-Fib…

From grids to pseudo-grids of lines: resolution and seminormality

Francesca Cioffi, Margherita Guida, Luciana Ramella

Over an infinite field $K$ , we investigate the minimal free resolution of some configurations of lines. We explicitly describe the minimal free resolution of "complete grids of lin…
