We show that the Brauer group BM (k, Hν, Rs,β) of the quasitriangular Hopf algebra (Hν, Rs,β) is a direct product of the additive group of the field k and the classical Brauer group associated to the bicharacter θs on defined by θs (x, y)= ωsxy, with ω a 2 ν th root of by: Galois theories, Hopf algebras, and semiabelian categories.

Here is a very brief indication of the origins of those connections. Hopf algebras arrived to the Galois theory of rings as early as the s — independently of, but in fact similarly to, the way in which algebraic group schemes were introduced to the theory of etaleFile Size: 2MB.

An algebra is a vector space V over a eld k together with a k- bilinear product of vectors under which V is a ring. A certain class of algebras, called Brauer algebras - algebras which split over a nite Galois extension - appear in many sub elds of abstract algebra, including K-theory and class eld Size: KB.

That ring need not be a eld of characteristic zero. Here are some examples. In number theory, groups arise as Galois groups of eld extensions, giving rise not only to representations over the ground eld, but also to integral representations over rings of integers (in case the elds are number elds).File Size: 1MB.

Brauer group. In mathematics, the Brauer group of a field K is an abelian group whose elements are Morita equivalence classes of central simple algebras over K, with addition given by the tensor product of algebras.

It was defined by the algebraist Richard Brauer. Let (H,R) be a finite dimensional quasitriangular Hopf algebra over a field k, and MH the representation category of H.

The deﬁnition of Hopf Galois extension has its roots in the approach of Chase, Harrison and Rosenberg who wanted to generalize the classical Galois theory of automorphism groups of ﬁelds to groups acting on commutative rings[4].

In Chase and Sweedler extended these ideas to coactions of Hopf algebras acting on a commutative k–algebra,File Size: KB. Included is a systematic development of the theory of Grothendieck topologies and etale cohomology, and discussion of topics such as Gabber's theorem and the theory of Taylor's big Brauer group of algebras without a unit.

Part II presents a systematic development of the Galois theory of Hopf algebras with special emphasis on the group of Galois. This is the first book to be dedicated entirely to Drinfeld's quasi-Hopf algebras.

The concept of Hopf algebras was first introduced in the theory of algebraic topology but in recent years has been developed by many mathematicians and applied to other areas of mathematics such as Lie groups, algebraic groups and Galois theory.

For many people there is life after 40; for some mathematicians there is algebra after Galois theory. The objective ofthis book is to prove the latter thesis. It is written primarily for students who have assimilated substantial portions of a standard first year graduate algebra textbook, and who have enjoyed the experience.

The material that is presented here should not be fatal if it is. to a unique central division algebra. Brauer group theory has strong connections to Galois theory, Homology theory, Group theory, Algebraic Geometry and K-Theory. Several versions and generalizations of the Brauer group of a eld were proposed through the last century, ending, from a formal point of view, in the construction of the.

Then Hopf–Galois descent theory for linear Hopf categories, the Hopf algebra version of a linear category, is developed. This leads to the notion of Hopf–Galois category extension. We have a dual theory, where actions by dual linear Hopf categories on linear categories are by: 1.

Description: The book provides a detailed account of basic coalgebra and Hopf algebra theory with emphasis on Hopf algebras which are pointed, semisimple, quasitriangular, or are of certain other quantum groups.

The development of the theory is carried out in such a way that the connection to the theory of the Brauer group in Part I is made clear. Last but not least: In general one can define the Brauer group of a braided monoidal category.

Now let G be a group and ϕ a pairing. One can consider the Hopf algebra KG and using ϕ one can define coquasi-triangular structure on KG. Denote by H the resulting coquasi-triangular Hopf algebra.
