DESCRIPTION:Martin Bright\nTo understand the Brauer-Manin obstruction comi
 ng from an Azumaya algebra on a variety over a number field\, we need to u
 nderstand the evaluation maps at each place. These appear to be largely go
 verned by the geometry of the reduction of the variety at each prime. I wi
 ll explain how this connection works\, mainly in the case of del Pezzo sur
 faces. Time permitting\, I will also show off some Magma code for computin
 g Azumaya algebras on surfaces.
