We characterize the number of points for which there exist non-empty Terracini sets of points in Pn. Then we study minimally Terracini finite sets of points in Pn and we obtain a complete description in the case of P3, when the number of points is less than twice the degree of the linear system.

Abstract
We characterize the number of points for which there exist non-empty Terracini sets of points in Pn. Then we study minimally Terracini finite sets of points in Pn and we obtain a complete description in the case of P3, when the number of points is less than twice the degree of the linear system.File in questo prodotto:
