Evaluating Azumaya algebras on cubic surfaces
نویسنده
چکیده
Let X be a cubic surface over a local number field k. Given an Azumaya algebra on X, we describe the local evaluation map X(k)→ Q/Z in two cases, showing a sharp dependence on the geometry of the reduction of X. This extends results of Colliot-Thélène, Kanevsky and Sansuc.

There Are Enough Azumaya Algebras on Surfaces
Using Maruyama’s theory of elementary transformations, I show that the Brauer group surjects onto the cohomological Brauer group for separated geometrically normal algebraic surfaces. As an application, I infer the existence of nonfree vector bundles on proper normal algebraic surfaces.
متن کاملBlt Azumaya Algebras and Moduli of Maximal Orders
We study moduli spaces of maximal orders in a ramified division algebra over the function field of a smooth projective surface. As in the case of moduli of stable commutative surfaces, we show that there is a Kollár-type condition giving a better moduli problem with the same geometric points: the stack of blt Azumaya algebras. One virtue of this refined moduli problem is that it admits a compac...
متن کاملAzumaya Monads and Comonads
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. Similar constructions are available in braided monoidal categories, and Azumaya algebras were defined in these settings. Here, we introduce Azumaya monads on any category A by considering a monad (F,m, e) on A endowed with a dis...
متن کاملQuasi-elementary H-Azumaya Algebras Arising from Generalized (Anti) Yetter-Drinfeld Modules
Let H be a Hopf algebra with bijective antipode, α, β ∈ AutHopf (H) and M a finite dimensional (α, β)-Yetter-Drinfeld module. We prove that End(M) endowed with certain structures becomes an H-Azumaya algebra, and the set of H-Azumaya algebras of this type is a subgroup of BQ(k,H), the Brauer group of H .
متن کاملThe Differential Azumaya Algebras and Non-commutative Picard–Vessiot Cocycles
A differential Azumaya algebra, and in particular a differential matrix algebra, over a differential field K with constants C is trivialized by a Picard–Vessiot (differential Galois) extension E. This yields a bijection between isomorphism classes of differential algebras and Picard–Vessiot cocycles Z(G(E/K), PGLn(C)) which cobound in Z (G(E/K), PGLn(E)).
