Seminar on Stacks (PhD Seminar)
Termin: Monday 14-16 in WSC-0-U-3.46
Dozenten L.C. Lefèvre, J. Heinloth.
In this seminar we will start by learning basic notions of stacks in the analytic and algebraic categories. We will try to pass to examples and applications quickly, learning the necessary machinery when we need it.
The program will be decided in blocks.
