Deformations of Prismatic Higher $(G,μ)$-Displays over Quasi-Syntomic Rings

Abstract: We prove a deformation theorem for prismatic higher $(G,\mu)$-displays over quasi-syntomic rings. As an application, we extend the classification of $p$-divisible groups via prismatic Dieudonn\'e modules to a class of rings properly containing quasi-syntonic rings. Finally, we related the stack of prismatic higher $(G,\mu)$-displays to integral local Shimura varieties.
