Workshop of the GRK 2240:

Welcome on the homepage for the Workshop of the GRK 2240. For more informations and activities of the former common AG Düsseldorf-Wuppertal: Algebra and Geometry see webpage. Here can you find the program for the winter semester 2018/19. The talks given at HHU are in the seminar room 25.22.03.73 and the talks given
at BUW are in lecture hall HS7. We would like to point out that from this semester the
(Ring-)Lecture is already at 13:30/14:00 at HHU/BUW. The Workshop of the
GRK2240 then starts at 15:30/16:00 at HHU/BUW
.

The topic for the summer semester 2019 is Inverse Galois problem over C(t) and étale fundamental groups.
Here is the → detailed program
