  • School - Masterclass 2017
    Dec 19, 2017 to Dec 21, 2017

    QR-Code

    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.

Thematic semester 2015 - PDE and Large Time Asymptotics

Partial differential equations arise in a wide range of problems that model physical phenomena. The thematic semester organized by the Centre Henri Lebesgue will focus on recent advances in various areas of both fundamental and applied research in this field: quantum mechanics and mathematical physics, fluid dynamics equations, kinetic theory. Specific attention will be paid to the mathematical techniques that allow for a decsription of the large time behavior of solutions.

Program

Master Program

The universities of Nantes and Rennes propose a specific Master program strengthened in analysis of partial differential equations and numerical analysis, related to the topics of the thematic semester. More information can be found here.
