Research- and Advanced Seminar of the Institute for Theoretical Computer Science

In the research seminar lectures on topics of interest for the research at the institute take place. Members and students of the institute as well as our guests give lectures. Participants as well as listeners are always welcome.

Please contact Prof. Kuske with any hints, inquiries, suggestions for lectures, etc.

It takes place on Tuesday, 15:00 – 16:30 in the Zusebau, room 2073. It provides a forum for:
