Displays and \(p\)-divisible groups (Q776411)

Summary: The theory of displays is a Dieudonné theory for formal \(p\)-divisible groups which is an equivalence of categories over an arbitrary \(p\)-adic ring. Over a more restricted class of rings one obtains a classification of all \(p\)-divisible groups. We explain basic ideas and some recent results of this theory. The last paragraph ameliorates the discussion of isogenies of displays found in the literature. For the entire collection see [Zbl 1416.60012].
