Berkeley Number Theory Seminar, Fall 2016

The weekly seminar will contain two types of talks. The first type will be the usual seminar talks given by invited speakers with (rather random) topics determined by them. The second type will be a series of coherent talks given by local people (mostly graduate students) around a fixed central topic. We will refer these as type I and type II in the schedule table below.

Central topic

The fixed central topic for this semester is TORSION CLASSES IN THE COHOMOLOGY OF SHIMURA VARIETIES, as in a recent work of Scholze. For a plan of the series, please click here. Please come to volunteer a talk.
