On generic G-graded Azumaya algebras [PDF]

open access: yesAdvances in Mathematics, 2022
Let $F$ be an algebraically closed field of characteristic zero and let $G$ be a finite group. Consider $G$-graded simple algebras $A$ which are finite dimensional and $e$-central over $F$, i.e. $Z(A)_{e} := Z(A)\cap A_{e} = F$. For any such algebra we construct a \textit{generic} $G$-graded algebra $\mathcal{U}$ which is \textit{Azumaya} in the ...

Homology of Azumaya algebras [PDF]

open access: yesProceedings of the American Mathematical Society, 1994
If R is a commutative k-algebra, any Azumaya R-algebra has the same Hochschild homology as R does.

Azumaya Algebras and Canonical Components [PDF]

open access: yesInternational Mathematics Research Notices, 2020
AbstractLet $M$ be a compact 3-manifold and $\Gamma =\pi _1(M)$. Work by Thurston and Culler–Shalen established the ${\operatorname{\textrm{SL}}}_2({\mathbb{C}})$ character variety $X(\Gamma )$ as fundamental tool in the study of the geometry and topology of $M$.

Azumaya algebras without involution [PDF]

open access: yesJournal of the European Mathematical Society, 2018
Generalizing a theorem of Albert, Saltman showed that an Azumaya algebra A over a ring represents a 2-torsion class in the Brauer group if and only if there is an algebra A’

Decomposition of topological Azumaya algebras [PDF]

open access: yesCanadian Mathematical Bulletin, 2021
AbstractLet $\mathscr {A}$ be a topological Azumaya algebra of degree $mn$ over a CW complex X. We give conditions for the positive integers m and n, and the space X so that $\mathscr {A}$ can be decomposed as the tensor product of topological Azumaya algebras of degrees m and n.

Azumaya Monads and Comonads

open access: yesAxioms, 2015
The definition of Azumaya algebras over commutative rings \(R\) requires the tensor product of modules over \(R\) and the twist map for the tensor product of any two \(R\)-modules.

Noncommutative motives of Azumaya algebras [PDF]

open access: yes, 2013
Let k be a base commutative ring, R a commutative ring of coefficients, X a quasi-compact quasi-separated k-scheme, A a sheaf of Azumaya algebras over X of rank r, and Hmo(R) the category of noncommutative motives with R-coefficients.

Higher Deformations of Lie Algebra Representations II [PDF]

open access: yes, 2020
Steinberg's tensor product theorem shows that for semisimple algebraic groups the study of irreducible representations of higher Frobenius kernels reduces to the study of irreducible representations of the first Frobenius kernel.
