Welcome on the homepage for the Workshop of the GRK 2240. For more informations and activities of the former common AG DüsseldorfWuppertal: Algebra and Geometry see
webpage. Here can you find the program for the summer semester 2019 or the winter semester 2018. We would like to point out that this semester all the
Special lectures start at 14:00 at BUW in seminar room F.13.11. The Workshop
