Jaya Iyer: Period index questions for hyperelliptic curves
We will discuss period-index question for Brauer group of fields. In particular we will consider function fields of hyperelliptic curves over number fields. We show that period equals index for 2-torsion Brauer elements under, local triviality conditions.
