Corestriction Principle in Non-abelian Galois Cohomology
نویسنده
چکیده
In this paper we prove that over local or global fields of characteristic 0, the Corestriction Principle holds for kernel and image of all maps which are connecting maps in group cohomology and the groups of R-equivalences. Some related questions over arbitrary fields of characteristic 0 are also discussed. AMS Mathematics Subject Classification (1991): Primary 11E72, Secondary 18G50, 20G10 Plan. Introduction. I.

First non-abelian cohomology of topological groups II
In this paper we introduce a new definition of the first non-abelian cohomology of topological groups. We relate the cohomology of a normal subgroup $N$ of a topological group $G$ and the quotient $G/N$ to the cohomology of $G$. We get the inflation-restriction exact sequence. Also, we obtain a seven-term exact cohomology sequence up to dimension 2. We give an interpretation of the first non-a...
متن کاملDescent Cohomology and Corings
A coring approach to non-Abelian descent cohomology of [P. Nuss & M. Wambst, Non-Abelian Hopf cohomology, Preprint arXiv:math.KT/0511712, (2005)] is described and a definition of a Galois cohomology for partial group actions is proposed.
متن کاملGalois Cohomology of Fields without Roots of Unity
There is a standard correspondence between elements of the cohomology group H(F, μn) (with the trivial action of ΓF = Gal(Fs/F ) on μn) and cyclic extensions of dimension n over F . We extend this to a correspondence between the cohomology groups H(F, μn) where the action of ΓF on μn varies, and the extensions of dimension n of K which are Galois over F , where K = F [μn] and [K :F ] is prime t...
متن کاملOn continuous cohomology of locally compact Abelian groups and bilinear maps
Let $A$ be an abelian topological group and $B$ a trivial topological $A$-module. In this paper we define the second bilinear cohomology with a trivial coefficient. We show that every abelian group can be embedded in a central extension of abelian groups with bilinear cocycle. Also we show that in the category of locally compact abelian groups a central extension with a continuous section can b...
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...
