Seminar on Stacks (PhD Seminar)
Termin: Montag 16-18 Uhr in WSC-N-U-4.05
Dozenten J. Heinloth
We will usually start the seminar with a discussion/Q&A/recap-session on one of the Thursday seminars.
Afterwards we discuss a topic/an article one of us wants to understand, the choice for the next topic is usually made at the end of the seminar.
The list below will thus be updated regularly, a list of links to articles and preprints discussed is included below.
This term will certainly include an introduction to algebraic stacks, e.g. following a preliminary program.
