Decomposition of Topological Azumaya Algebras with Orthogonal Involution

Let $\mathcal{A}$ be a topological Azumaya algebra of degree $mn$ with an orthogonal involution over a CW complex $X$ of dimension less than or equal to $\min\{m,n\}$.

On Azumaya graphs

, 2003
We study Azumaya multiplicative graphs over a suitable base category, generalizing in this way the theory of Azumaya algebras over a ring, with or without unit, and the theory of enriched Azumaya categories.

Moduli of étale subalgebras in an Azumaya algebra

, 2004
Let $A$ be a sheaf of Azumaya algebras over a Noetherian base $S$. In this paper we describe using generalized Severi-Brauer varieties, a quasi-projective moduli space parametrizing sheaves of ètale subalgebras of $A$. In the case that $S$ is the spectrum of a field, we study the geometry of this moduli space, and show that in certain cases it is a ...

A family of Azumaya algebras arising from quantum groups

, 1996
We present a family of Azumaya algebras. These algebras arise from the representation theory of a multiparameter quantum deformation of the coordinate ring of an algebraic group G at roots of 1.

Classifying spaces for topological Azumaya algebras

, 2020
In this thesis, we study a family of smooth varieties, whose members are denoted B_n^r(C), that bears a similar relationship to topological Azumaya algebras as the Grassmannians G_{n,r}(C) do to complex vector bundles. Specifically, we will show that the
