Gorenstein points in ${\mathbb{P}}^3$ via Hadamard product of projective varieties

Cristiano Bocci, Chiara Capresi, Daniele Carrucoli

We show how to construct a stick figure of lines in ${\mathbb{P}}^3$ using the Hadamard product of projective varieties. Then, applying the results of Migliore and Nagel, we use such…
