Resumen de Gorenstein points in P3 via Hadamard products of projective varieties
Cristiano Bocci, C. Capresi, D. Carrucoli
We show how to construct a stick figure of lines in P3 using the Hadamard product of projective varieties. Then, applying the results of Migliore and Nagel, we use such a stick figure to build a Gorenstein set of points with given h−vector hh. Since the Hadamard product is a coordinate-wise product, we show, at the end, how the coordinates of the points, in the Gorenstein set, can be directly determined.
