Teaching

I am teaching a course on geometric group theory in the winter semester of 2025/6. The course will take place on Thursdays at 14.00-16.00 in the Kleiner Hörsaal in Wegelerstraße 10. I will try to upload notes as the course progresses.

Lecture 1: Group presentations, actions, Cayley graphs, and quasi-isometries.

Lecture 2: Quasi-geodesics, the Milnor-Schwarz lemma, classical hyperbolic geometry.

Lecture 3: Some more classical hyperbolic geometry, hyperbolic metric spaces, the Morse Lemma.
