Witt groups of Severi-Brauer varieties and of function fields of conics [PDF]

Épijournal de Géométrie Algébrique
The Witt group of skew hermitian forms over a division algebra $D$ with symplectic involution is shown to be canonically isomorphic to the Witt group of symmetric bilinear forms over the Severi-Brauer variety of $D$ with values in a suitable line bundle.

The Brauer group is torsion [PDF]

Proceedings of the American Mathematical Society, 1981
In [3], a well-known fact about the Brauer group of a field was generalized to show that the Brauer group of a commutative ring was torsion. In fact, if A is Azumaya of constant rank n2 over R, then A (= A OR O * R A) ~ EndR(P) for P an progenerator. In this note we will present a relatively elementary proof of this theorem, and we will also describe P

The maximal subgroups of the classical groups in dimension 13, 14 and 15 [PDF]

, 2015
One might easily argue that the Classification of Finite Simple Groups is one of the most important theorems of group theory. Given that any finite group can be deconstructed into its simple composition factors, it is of great importance to have a ...

The Picard group of Brauer-Severi varieties

Open Mathematics, 2018
In this paper, we provide explicit generators for the Picard groups of cyclic Brauer-Severi varieties defined over the base field. In particular,we provide such generators for all Brauer-Severi surfaces.

Symmetric Presentations of Coxeter Groups [PDF]

, 2011
We apply the techniques of symmetric generation to establish the standard presentations of the finite simply laced irreducible finite Coxeter groups, that is, the Coxeter groups of types An, Dn and En, and show that these are naturally arrived at purely ...

Brauer theory for profinite groups

Journal of Algebra, 2014
Brauer Theory for a finite group can be viewed as a method for comparing the representations of the group in characteristic 0 with those in prime characteristic. Here we generalize much of the machinery of Brauer theory to the setting of profinite groups.
