On the connectedness of $p$-adic period domains

Number Theory 2022-12-29 v2 Algebraic Geometry

Abstract

We prove that all pp-adic period domains (and their non-minuscule analogues) are geometrically connected. This answers a question of Hartl [Har13] and has interesting consequences to the geometry of Shimura and local Shimura varieties.
