The Oberseminar in SoSe21 is on applications of the étale fundamental group to algebraic geometry.
We focus mostly on understanding two recent articles of Daniel Litt as well as de Jong's conjecture.
Here is the program.
The seminar takes place on Wednesdays 10:15 - 11:45 via Zoom.
The same Zoom-link works each week. Please write to ruelling(a-in-o)uni-wuppertal.de if you are interested to attend via Zoom.
