Algebraic geometry seminar today at Sissa + on Zoom

[Barbara Fantechi]

Next seminar, Friday Jan 28 at 4:30pm, room Boris Dubrovin 136

Speaker: Andrea Grossutti (Sissa)

Title: Yoneda lemma, representable functors and group objects

Abstract: This is the first talk in a series of seminars about the
theory of stacks in algebraic geometry. In the first part of the talk
I will discuss the theory of representable functors (in particular
Yoneda lemma and universal object of a functor), in the second part
group objects in a category and their actions are discussed, using the
results introduced in the first part.
I will follow the notes by Angelo Vistoli on algebraic stacks:

The only prerequisites are the basic properties of functors and
natural transformations, see e.g. chapter 1 in
