In the seminar we treat the theory of quivers and grassmaninan varieties.

The seminar is aimed for both bachelor and master students. It is given in English. Each participant has to give a 60 minutes talk (90 minutes for master students) and additionally hand in an elaboration in LaTeX. (up to 10 pages for bachelor students, up to 15 pages for master students). The deadline for the elaborations is on 08/14/2020.
