# Azumaya toposes

@inproceedings{Hemelaer2017AzumayaT, title={Azumaya toposes}, author={Jens Hemelaer}, year={2017} }

In [4], many different Grothendieck topologies were introduced on the category of Azumaya algebras. Here we give a classification in terms of sets of supernatural numbers. Then we discuss the associated categories of sheaves and their topos-theoretic points, which are related to UHF-algebras. The sheaf toposes that correspond to a single supernatural number have an alternative description, involving actions of the associated projective general linear group.
