Let L be a non-archimedean local field of characteristic 0. We present a variant of the theory of (\phi,\Gamma)-modules associated with Lubin-Tate groups, developed by Kisin and Ren [Ki-Re], in which we replace the Lubin-Tate tower by the maximal abelian extension \Gamma = Gal(L^ab/L). This variation allows us to compute the functors of induction and restriction for (\phi,\Gamma)-modules, when the ground field L changes. We also give a self-contained account of the Cherbonnier-Colmez theorem on…

Using Lubin-Tate groups, we develop a variant of Fontaine's theory of (ϕ,)-modules, and we use it to give a description of the Galois stable lattices inside certain crystalline representations. K of

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
