| Popis: | 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 $\mathbb P^{1}\times\cdots \times\mathbb P^{1}$ and in the case $\mathbb P^{n_1}\times \cdots \times \mathbb P^{n_k}$ with $n_i\in \{1,2\}$ for all $i$. We also check very ampleness for zero-dimensional schemes of general points in the multiprojective spaces. Comment: 11 pages |
