Duality Theorems in Galois Cohomology over Number Fields

چکیده
the direct limit taken over all finite Galois extensions K of k in which the integral closure Y of X is unramified over X, where GKJk denotes the Galois group of such an extension, and where GY denotes the group of points of G with coordinates in Y. For example, if X=k, our notation coincides with that of [10]. For any X, the group H(X,C) is the r-th cohomology group of the profinite group Gjr=lim GKlk (fundamental group of Spec X) with

Cohomology and duality for (φ,Γ)-modules over the Robba ring
Given a p-adic representation of the Galois group of a local field, we show that its Galois cohomology can be computed using the associated étale (φ,Γ)-module over the Robba ring; this is a variant of a result of Herr. We then establish analogues, for not necessarily étale (φ,Γ)-modules over the Robba ring, of the Euler-Poincaré characteristic formula and Tate local duality for p-adic represent...
متن کاملRiemann-Roch Theorem, Stability and New Zeta Functions for Number Fields
In this paper, we introduce new non-abelian zeta functions for number fields and study their basic properties. Recall that for number fields, we have the classical Dedekind zeta functions. These functions are usually called abelian, since, following Artin, they are associated to one dimensional representations of Galois groups; moreover, following Tate and Iwasawa, they may be constructed as in...
متن کاملWhitehead’s Lemmas and Galois Cohomology of Abelian Varieties
Whitehead’s lemmas for Lie algebra cohomology translate into vanishing theorems for H and H in Galois cohomology. Via inflation-restriction, the H vanishing theorem leads to a simple formula for H(K, T`), where T` is the `-adic Tate module of an abelian variety over a number field K. We apply this formula to the “support problem” for abelian varieties. Under a suitable semisimplicity hypothesis...
