DESCRIPTION:Speaker: Sachi Hashimoto\nhosted by Tim Browning\nAbstract: We 
 study the arithmetic properties of a family of Calabi-Yau threefolds origi
 nally studied by Hosono and Takagi in the context of mirror symmetry. The 
 geometry of these varieties endows them with a 2-torsion Brauer class. Und
 er mild conditions\, we show this Brauer class prevents the rational point
 s from being dense in the adelic points. This is joint work with Katrina H
 onigs\, Alicia Lamarche\, and Isabel Vogt.
