DESCRIPTION:Title: <a href="https://researchseminars.org/talk/agstanford/1
 2/">Splitting Brauer classes</a>\nby Wei Ho (University of Michigan) as pa
 rt of Stanford algebraic geometry seminar\n\n\nAbstract\nGiven a Brauer cl
 ass over a field\, what types of varieties split it? Or more geometrically
 \, can we say anything about the varieties that map to a given Brauer-Seve
 ri variety? In this talk\, we will discuss some open questions related to 
 splitting Brauer classes. For example\, we will review some classical alge
 bro-geometric constructions that produce genus one curves splitting low in
 dex Brauer classes ((old) joint work with A.J. de Jong)\, and we will expl
 ain why a Brauer class of any index is split by a torsor under an abelian 
 variety (joint work with M. Lieblich).\n\nThe discussion for Wei Ho’s ta
 lk is taking place not in zoom-chat\, but at https://tinyurl.com/2020-06-1
 2-wh  (and will be deleted after 3-7 days).\n
