The Oberseminar in WS20/21 is on Fargues-Fontaine curves. We follow closely lecture notes of Anschütz, see here for 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.
