This is the web page of the weekly Oberseminar on Arithmetische Geometrie of Prof. Dr. Michael Stoll joint with Prof. Dr. Michael Dettweiler.

It takes place every Friday from 12:30 to 14:00 in room S82-NW II and is followed by a Tea in our seminar room (

The goal of this Seminar is to give the keys to current and dynamic research topics of Arithmetic-Geometry. It is intended as a research seminar to acquire a precise and clear view of the field, and welcomes students eager of developing their understanding of mathematical theories in a research situation.

Current oberseminar organizer: Solomon Vishkautsan
