School - Masterclass 2017

Angers, from December 19th to December 21st

Organization board: Etienne Mann

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.
Loic Chaumont: Application of the matrix-tree-theorem

The organisation board will pay the housing and the lunch. The other meals are not payed by the organizers. For the travel expenses, we will do our best in the limit of our budget.

Date limite d'inscription 15 novembre.

Jérémy Le Borgne, Peut-on ne pas inverser la courbe du chômage ?

Lorsqu'on cherche à inverser la courbe du chômage, on essaie de faire décroître le taux de chômage, mais on se contente parfois d'une croissance moins rapide... Cette épineuse question nous servira de prétexte à présenter un théorème de Bernstein décrivant les fonctions dont toutes les dérivées sont positives.
