We study the Drinfeld half-spaces in the Fall of 2023.
The main goal of this semester is to learn topics related to Drinfeld half-spaces: basic properties, the Drinfeld theorem, and the Čerednik–Drinfeld uniformization theorem for Drinfeld half-plane [BC91]; the cohomology of the Drinfeld half-spaces [SS91, Dat06].
[BC91] Boutot and Carayol, Uniformisation p-adique des courbes de Shimura: les théorèmes de Čerednik et de Drinfeld
[SS91] Schneider and Stuhler, The cohomology of p-adic symmetric spaces
