Seminar "A panoramic view on buildings"

Buildings are mathematical objects that have a rich geometric and combinatorial structure and they appear naturally in many mathematical subdisciplines, ranging from number theory over geometric group theory up to analysis. In this seminar we want to develop a panoramic view on buildings, i.e. we want to see how these buldings show up in the different subdisciplines.

The seminar takes place in a hybrid format in cooperation with Bielefeld University and the university of Bonn and is supported by CRC-TRR 358.
