Invitation to higher local fields, Part I, section 13: Abelian extensions of absolutely unramified complete discrete valuation fields
Abstract
This is an introduction to the author theory of cyclic pextensions of an absolutely unramified complete discrete valuation field K with arbitrary residue field of characteristic p. In this theory a homomorphism is constructed from the ppart of the group of characters of K to Witt vectors over its residue field.
