News

The lecture will be presented as videos that you can find below as well as on the chairs' YouTube channel. In addition, there will be zoom meetings that take place very Thursday, 08:15 h (for questions, etc.). The first one will take place on November, 5th. To get access to the online-live meeting please register for the lecture via the OLAT system.
