Seminars & Events

Upcoming

The European Autumn School in Topology (EAST) is a yearly event (usually held in September) aimed at introducing graduate students to topics of active research. I organize this school together with Lennart Meier, Ieke Moerdijk, and Steffen Sagave.

We have an ongoing joint topology seminar with Nijmegen called TopICS (Topology InterCity Seminar).
