Séminaire champêtre (stacky seminar)

Institut Fourier. Université Grenoble Alpes, Grenoble, France.



The goal of this seminar is to learn about stacks, both in the context of algebraic geometry (moduli spaces, quotients) and of topology (orbifolds, algebraic topology).

We do not have one unique source to follow. For the first talks we worked on the general theory of stacks using the book of F. Neumann below, for which the prerequisite are mainly classical category theory and schemes. Then everyone should work on the problems he is interested in, with his own point view, and is welcome explain it to the others. Some have a background in algebraic geometry over any field, others prefer algebraic topology or complex algebraic geometry or differential geometry, and none of these points of view should be excluded.
