Abstract

We study families of analytic pp-divisible groups over adic spaces SS defined over Qp\mathbb{Q}_p. We prove an equivalence between such families and Hodge-Tate triples, generalizing a theorem of Fargues. For a perfectoid space SS, we construct a functor associating to an analytic pp-divisible group GS\mathcal{G} \rightarrow S a coherent sheaf E(G)\mathcal{E}(\mathcal{G}) on the relative Fargues--Fontaine curve XSX_S. Restricting to analytic pp-divisible groups admitting a Cartier dual, we obtain an equivalence of categories with local shtukas satisfying a minuscule condition, compatible with the prismatic Dieudonn\'e theory of Ansch\"utz--Le Bras. We conclude with applications to moduli spaces: we show that the local Shimura varieties of EL and PEL types of Scholze--Weinstein are moduli spaces of analytic pp-divisible groups with extra structure, and we give a reinterpretation of the Hodge--Tate period map of Scholze in terms of topologically pp-torsion subgroups of abelian varieties.
