Wintenberger's Functor for Abelian Extensions

Number Theory 2008-05-20 v1

Abstract

Let kk be a finite field. Wintenberger used the field of norms to give an equivalence between a category whose objects are totally ramified abelian pp-adic Lie extensions E/FE/F, where FF is a local field with residue field kk, and a category whose objects are pairs (K,A)(K,A), where Kk((T))K\cong k((T)) and AA is an abelian pp-adic Lie subgroup of \Autk(K)\Aut_k(K). In this paper we extend this equivalence to allow \Gal(E/F)\Gal(E/F) and AA to be arbitrary abelian pro-pp groups.
