Sheared displays and $p$ -divisible groups

Manuel Hoff, Eike Lau

We develop a Dieudonné theory for $p$ -divisible groups using sheared Witt vectors.

On the Right Derived Functors of Ordinary Parts

Manuel Hoff, Sarah Diana Meier, Michael Spieß +1

We prove a variant of Emerton's conjecture concerning the right derived functors of the ordinary parts functor $Ord_{P}^{G}$ . This functor plays an important role in the…

Moduli spaces of nilpotent displays

Sebastian Bartling, Manuel Hoff

We show that the moduli problem of deformations of nilpotent displays by quasi-isogenies is representable, without using $p$ -divisible groups. The main ingredients are Artin's crit…

On parahoric $(G, μ)$ -displays

Manuel Hoff

We develop tools to study spaces of $p$ -divisible groups and Abelian varieties with additional structure. More precisely, we extend the definition of parahoric (Dieudonné) $(\mathc…
