Dieudonne theory and prismatic F-gaueges We will give an introduction to Dieudonne theory and explain how a stack theoretic approach leads to general classification theorems.

Apertures and the inverse syntomic Dieudonne functor

In recent work, K. Madapusi and I show that the $p$-adic formal moduli of apertures agrees with the moduli of p-divisible groups...
