# BKMR Research Seminar on Geometric Group Theory

### Groups, Buildings and Compactifications

#### Münster, August 9th - 11th 2017

This seminar is intended as a continuation of a joint seminar series of the mathematical departments of the universities Bielefeld, Karlsruhe, Münster and Regensburg.

This time, we study how buildings arise naturally as the boundary of semi-simple Lie groups. In general, we are interested in spaces with nice group actions for certain classes of groups and the construction of compactifications of those spaces. The examples we want to investigate in more detail are arithmetic subgroups, mapping class groups and outer automorphism groups of free groups. We will follow a survey article by Lizhen Ji. Please find more information on the program here.

If you are interested in participating in the seminar, please contact the organizers until the 1st of August 2017.
