We are currently having a study group on differential geometry, see here for more details.

In the autumn of 2015, we had a study group on Hall algebras. In the academic year of 2014-2015, we had a study group on algebraic groups. In the academic year of 2013-2014, we had two study groups: one in homological algebra and one in geometry in representation theory.
