Algebraic geometry

**Hosts: Tim Browning, Tamas Hausel**

**Location: Building West, Heinzel Seminar RoomTime: Thursdays, 1.30pm-3.30pm ** (* =unusual time/place, check invitation file)

The seminar has a 2 hour format. The first hour is asked to be introductory aimed at graduate students. The second part, after a break, could be more technical. In particular it makes sense to come only for the first introductory part.

PLEASE NOTE: During to concerns about the COVID-19 virus we will be conducting seminars remotely via mathseminars.org/seminar/AGNTISTA.
