We organize a masterclass in Angers, from 19th to 21st of December, 2017.
Lectures will be in the morning sessions.
We will have two parallel sessions:
Etienne Mann : Introduction to algebraic stacks
We will introduce the notion of fibered category, Grothendieck topology and stacks. We will illustrate these notions on simple examples.
These lectures are for Master (or PhD) students who had followed a introduction to algebraic geometry that is algebraic varieties and sheaves.
