Geometry and Group Theory

A cabinet of curiosities of groups

Bachelor- und Master Seminar on exotic groups and their constructions.

How wild can a group be?

This seminar is a guided tour through some of the most fascinating and unusual examples of geometric group theory.

We focus on groups with surprising constructions, exotic actions, or unexpected algebraic properties. We encounter Thompson's groups, braid groups, and groups that act on graphs, non-positively curved spaces, or fractal spaces.

We offer an introduction to a wide variety of current topics and build bridges to research. Prior knowledge of geometric group theory or topology is necessary for some of the talks.

Information

The talks will happen in (probably) three blocks throughout the semester. A preliminary meeting for assigning talks will take place on Tuesday, April 14 at 16:15 (room TBA).

More information and a seminar program will be published soon!

Please register on Müsli if you wish to participate in the seminar.
