Twists of Drinfeld–Stuhler Modular Varieties

  • Michael Spieß


Let be a maximal (or more generally a hereditary) order in a central simple algebra over a global field of positive characteristic. We show that certain modular scheme of -elliptic sheaves – for different – are twists of each other and deduce that the *uniformization at * and the Cherednik-Drinfeld uniformization for these varieties are equivalent.
