#### Abstract

Drinfeld proved that the p-adic upper half space $\Omega^d_F$ for a $p$-adic local field $F$ is the general fiber of a formal scheme which is the moduli space of *special formal $O_D$-modules*, where $D$ is a central division algebra with invariant $1/d$ over $F$.We give examples of other moduli problems of $p$-divisible formal groups which have general fiber $\Omega^d_F$. We show that, when $F / \mathbb{Q}_p$ is unramified, our moduli spaces actually agree with Drinfeld’s space. Using our results in the ramified case, P. Scholze has proved this in general. We also consider a variant for the Lubin–Tate moduli problem.
