Boundedness of the p-primary torsion of the Brauer group of products of varieties

open access: yesForum of Mathematics, Sigma
Let k be a field finitely generated over its prime subfield. We prove that the quotient of the Brauer group of a product of varieties over k by the sum of the images of the Brauer groups of factors has finite exponent.

Graded Brauer Groups.

open access: yescrll, 1964
Author's introduction: This paper arose out of the observation that the definition of a Clifford algebra as an invariant of a quadratic form is made awkward by the fact that the algebra corresponding to the orthogonal direct sum of two quadratic forms is not simply the tensor product of their separate Clifford algebras.

The Brauer Group of a Field [PDF]

open access: yes, 2016
In this paper we discuss the Brauer group of a field and its connections with cohomology groups. Definitions involving central simple algebras lead to a discussion of splitting fields, which are the important step in the connection of the Brauer group ...

More on the Schur group of a commutative ring

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1985
The Schur group of a commutative ring, R, with identity consists of all classes in the Brauer group of R which contain a homomorphic image of a group ring RG for some finite group G.

Brauer groups and Néron class groups [PDF]

open access: yesInternational Journal of Number Theory, 2020
Let [Formula: see text] be a global field and let [Formula: see text] be a finite set of primes of [Formula: see text] containing the Archimedean primes. We generalize the duality theorem for the Néron [Formula: see text]-class group of an abelian variety [Formula: see text] over [Formula: see text] established previously by removing the requirement ...

The Brauer–Clifford group of G-rings [PDF]

open access: yes, 2011
In previous work, the author introduced the Brauer–Clifford group of certain G-algebras. This group is useful because to every irreducible character of a normal subgroup of a finite group, one can associate a unique element of a specific Brauer–Clifford ...

Brauer Analysis of Thompson’s Group F and Its Application to the Solutions of Some Yang–Baxter Equations

open access: yesMathematics
The study of algebraic invariants associated with Brauer configuration algebras induced by appropriate multisets is said to be a Brauer analysis of the data that define the multisets.
