The Equivariant Brauer Group of a Group
We consider the Brauer group BM(k, G) of a group G (finite or infinite) over a commutative ring k with identity. A split exact sequence 1 −→ Br′(k) −→ BM′(k, G) −→ Gal(k, G) −→ 1 is obtained. This generalizes the Fröhlich-Wall exact sequence ([7, 8])from the case of a field to the case of a commutative ring, and generalizes the PiccoPlatzeck exact sequence ([13]) from the finite case of G to th...
متن کاملEquivariant Brauer groups and cohomology ✩
In this paper we present a cohomological description of the equivariant Brauer group relative to a Galois finite extension of fields endowed with the action of a group of operators. This description is a natural generalization of the classic Brauer–Hasse–Noether’s theorem, and it is established by means of a three-term exact sequence linking the relative equivariant Brauer group, the 2nd cohomo...
متن کاملEquivariant Cohomology and Representations of the Symmetric Group
f : Cn(R ) → U(n)/T n from the configuration space of n ordered distinct points of R to the flag manifold of U(n) which is compatible with the natural action of the symmetric group Σn on both spaces. I also noted in [1] that the action of Σn on the rational cohomology of either space coincides with the regular representation but that the homomorphism f induced by f cannot possibly be an isomorp...
متن کاملEquivariant Formal Group Laws and Complex Oriented Cohomology Theories
The article gives an introduction to equivariant formal group laws, and explains its relevance to complex oriented cohomol-ogy theories in general and to complex cobordism in particular.
متن کاملBrauer Algebras and the Brauer Group
An algebra is a vector space V over a field k together with a kbilinear product of vectors under which V is a ring. A certain class of algebras, called Brauer algebras algebras which split over a finite Galois extension appear in many subfields of abstract algebra, including K-theory and class field theory. Beginning with a definition of the the tensor product, we define and study Brauer algebr...
