### Group Seminar

The seminar series is a joint event of the combinatorial optimization/discrete mathematics groups at RWTH Aachen University:

- Lehrstuhl II für Mathematik (Prof. Triesch, Prof. Koster, Prof. Büsing),
- Chair of Operations Research (Prof. Lübbecke) and
- Chair of Management Science (Prof. Peis).

In WiSe 2014/15 the seminar takes place every thursday at 10:15am.

Announcements can be received by subscribing to our mailing list math2-oberseminar.
