Seminar tomorrow: Isabel Vogt (UW)

[Bianca Viray]

Hi everyone,

Tomorrow at 10am we'll have Isabel Vogt speaking about Transcendental Brauer-Manin obstructions on a Calabi-Yau threefold (abstract below).  As usual, please come ready to ask a lot of questions!

Gather.town for lunch, 12:30 - 1:30pm, Tuesdays of seminar

Abstract: In this talk, I will discuss arithmetic aspects of a family Calabi-Yau threefolds originally studied by Hosono and Takagi in the context of mirror symmetry.  These varieties come equipped with a natural 2-torsion Brauer class, and we show that under mild conditions on the threefold, this prevents the rational points from being dense in the adelic points.  This is joint work with Sachi Hashimoto, Katrina Honigs, and Alicia Lamarche.
