Ursula Ludwig accepts offer from the University of Nice (France)

Prof. Dr. Ursula Ludwig (University of Münster/University of Duisburg-Essen) has accepted an offer from the University of Nice (France) and has started her professorship there as of September 1, 2024. We congratulate her to this success and we are glad that she will remain an associated member of the RTG 2553.

Research Training Group 2553 will be continued

The German Research Foundation DFG has decided that our Research Training Group 2553 “Symmetries and classifying spaces: analytic, arithmetic and derived” will be funded for a second period of four and a half years, until March 2024. We are very happy about this emphatic confirmation of our work in the Research Training Group, and above all about being able to support current and future doctoral students in the Research Training Group in the coming years. The next 5 doctoral positions are to be filled as early as October 2024.
