DESCRIPTION:Title: <a href="https://researchseminars.org/talk/zoomnovy/10/
 ">Period-Index questions for function fields of hyperelliptic curves</a>\n
 by Raman Parimala (Emory University) as part of Algebraic groups and algeb
 raic geometry: in honor of Zinovy Reichstein's 60th birthday\n\n\nAbstract
 \nWe shall discuss period/index questions for the Brauer group of function
  fields of hyperelliptic curves over number fields. We will relate this qu
 estion to a Hasse principle for certain orthogonal Grassmannians of pencil
 s of quadrics. We derive some consequences concerning the u-invariant in t
 he case of genus 2 curves.\n
