    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 with breakfast and the lunches. The dinners are not payed by the organizers. For the travel expenses, we will do our best in the limit of our budget.

    Deadline 15th novembre. Limit 30 participants maximum.

    3) A few mini-courses about different related questions (eigenvalues, integral equations, fast methods, singularities) given by members of the organization board.

Thematic Semester 2014 - Around moduli spaces

Moduli spaces are among the subjects with a longest history in algebraic geometry. Starting from the first ideas of Riemann to nowadays, the research in this field has always been a backbone for the entire discipline. Its amazing development has also motived many technical advances and discoveries. Still these days the relevant amount of researchers working on moduli theory witnesses a very active and vital field of research. The goal of the current semester of the CHL is to explore many different aspects of this field of research, during several conferences, schools and workshops, to be held in Rennes, Nantes, Angers and Brest.

Program

The universities of Nantes and Rennes propose a special Master program strengthened in algebra and geometry related to the topic of the thematic semester. More informations here.
