Algebraic geometry seminar in person plus on zoom

[Alessandro Nobile]

Next seminar, tomorrow at 4:30pm, room Boris Dubrovin 136

Speaker: Alessandro Nobile (Sissa)

Title: Sites and sheaves on sites

Abstract: This is the second talk in the series of seminars about the theory of stacks in algebraic geometry. In this talk I will introduce and motivate the notion of Grothendieck topologies on a category and give examples. I will then discuss the notion of sheaves on sites.
We will cover paragraph 2.3 of Vistoli's notes (http://homepage.sns.it/vistoli/descent.pdf)
