The crystalline period map is a tool for linearizing $p$-divisible groups. It has been applied to study the Langlands correspondences, and has possible applications to the homotopy groups of spheres. The original construction of the period map is inherently local. We present an alternative construction, giving a map on the entire moduli stack of $p$-divisbile groups, up to isogeny, which specializes to the original local construction.

The geometry of the Lubin-Tate space of deformations of a formal group is studied via an \'etale, rigid analytic map from the deformation space to projective space. This leads to a simple description… Expand

We discuss the first author's Picard groups of stable homotopy. We give s. detailed description of the calculation of PiC!, and go on to describe geometric constructions for lifts of the elements of… Expand

We prove several results about p-divisible groups and Rapoport-Zink spaces. Our main goal is to prove that Rapoport-Zink spaces at infinite level are naturally perfectoid spaces, and to give a… Expand

Given any Fp-point x = [(Ax, λx)] in the moduli space Ag of gdimensional principally polarized abelian varieties in characteristic p > 0, the Hecke orbit of x, which consists of all points [(B, ν)] ∈… Expand
