A Galois code for valuations
Valuations on a field K are encoded in the absolute Galois group GK of K: They are in one-to-one correspondence to the conjugacy classes of decomposition subgroups of GK which (apart from few
Chapter 10 Z / ` abelian-by-central Galois theory of prime divisors
In this manuscript I show how to recover some of the inertia structure of (quasi) divisors of a function field K|k over an algebraically closed base field k from its maximal mod ` abelian-by-central
Almost-Commuting-Liftable Subgroups of Galois Groups
Let K be a field and \ell be a prime such that char K \neq \ell. In the presence of sufficiently many roots of unity in K, we show how to recover some of the inertia/decomposition structure of
On the 3-Pfister Number of Quadratic Forms
For a field F of characteristic different from 2, containing a square root of -1, endowed with an F×2-compatible valuation v such that the residue field has at most two square classes, we use a
Brauer Group Analogues of Results Relating the Witt Ring to Valuations and Galois Theory
Abstract Let F be a field of characteristic different from p containing a primitive p-th root of unity. This paper studies the cup product pairing H l(F, p) x H l (F, p) → H 2(F, p) and its
Pro-ℓ abelian-by-central Galois theory of prime divisors
In the present paper it is shown that one can recover much of the inertia structure of (quasi) divisors of a function field K|k over an algebraically closed base field k from the maximal pro-ℓ
Quotients of Milnor K-rings, orderings, and valuations
We define and study the Milnor K-ring of a field F modulo a subgroup of the multiplicative group of F. We compute it in several arithmetical situations, and study the reflection of orderings and
A galois-theoretic characterization ofp-adically closed fields
AbstractLetp be an odd prime,K a field, andGK its absolute Galois group. It is shown thatK isp-adically closed if and only ifGK is isomorphic to an open subgroup of $$G_{\mathbb{Q}_p } $$ . It is
From p-rigid elements to valuations (with a Galois-characterization of p-adic fields).
Let p be an odd prime, F a field with charF=^=/? containing a primitive p-th root of unity and assume aeF\F. If F admits some p-henselian valuation with residual characteriztic Φ p for which the
Additive Structure of Multiplicative Subgroups
One of the fundamental questions in current field theory, related to Grothendieck's conjecture of birational anabelian geometry, is the investigation of the precise relationship between the Galois
