| Feb 21, 2010 at 17:01 | comment | added | Andrea Ferretti | If you read my question, I was asking for a fine moduli space of K3 with some (algebraic) additional structure. Moreover, how do you construct moduli spaces of polarized K3 over $\mathbb{Z}$? I only know how to do it over $\mathbb{C}$. | |

Over $\mathcal C$, it can be written as the quotient $G\D$, $D$ a Hermitian symmetric domain, $G$ an arithmetic group. Choosing a finite index subgroup $G'$ of $G$, the space $G'\D$ may be considered to be a fine moduli space. | |
