Abelian Galois cohomology of reductive groups. [Mikhail Borovoi] Introduction 1. The algebraic fundamental group of a reductive group 2. Abelian Galois cohomology 3. The abelianization map 4. Computation of abelian Galois cohomology 5. Book\/a>, schema:MediaObject\/a>, schema:CreativeWork\/a> ;. In mathematics, a reductive group is a type of linear algebraic group over a definition is that a connected linear algebraic group G over a perfect field is reductive if it has a representation with finite kernel which is a direct sum of irreducible ive groups include some of the most important groups in mathematics, such as the general linear group GL(n) of. Destination page number Search scope Search Text. In mathematics, Galois cohomology is the study of the group cohomology of Galois modules, that is, the application of homological algebra to modules for Galois groups.A Galois group G associated to a field extension L/K acts in a natural way on some abelian groups, for example those constructed directly from L, but also through other Galois representations that may be .

This lacuna was ﬁlled by the book of Conrad, Gabber, and Prasad (, ), which completes earlier work of Borel and Tits. In the meantime, in a seminar at IAS in –60, Weil had re-expressed some of Siegel’s work in terms of ad`eles and algebraic groups, and Langlands. See section in Chapter I of Serre's book on Galois cohomology for the Galois case, Milne's "Etale cohomology" book for generalization with flat and \'etale topologies, and Appendix B in my paper on "Finiteness theorems for algebraic groups over function fields" for a concrete fleshing out of the dictionary between the torsor and Galois. We are interested in describing the homology groups and cohomology groups for an elementary abelian group of can be viewed as the additive group of a -dimensional vector space over a field of elements. It is isomorphic to the external direct product of .

In Schur studied a group isomorphic to H2(G,Z), and this group is known as the Schur multiplier of G. In Baer studied H2(G,A) as a group of equivalence classes of extensions. It was in that Eilenberg and MacLane introduced an algebraic approach which included these groups as special cases. The deﬁnition is thatFile Size: KB.
