In this paper, we study finite 0-dimensional schemes in product of multiprojective spaces and their ideals. In particular, we describe the set of generators of the ideal defining a 0-dimensional scheme in the case P-1 x ... x P-1 and in the case P-n1 x ... x P-nk with n(i) is an element of {1,2} for all i. We also check very ampleness for zero-dimensional schemes of general points in the multiprojective spaces.

Abstract
In this paper, we study finite 0-dimensional schemes in product of multiprojective spaces and their ideals. In particular, we describe the set of generators of the ideal defining a 0-dimensional scheme in the case P-1 x ... x P-1 and in the case P-n1 x ... x P-nk with n(i) is an element of {1,2} for all i. We also check very ampleness for zero-dimensional schemes of general points in the multiprojective spaces.File in questo prodotto:
