  • Lebesgue Master Scholarship
    Nov 15, 2017 to Mar 15, 2018
    lebesgue_money.png The Lebesgue Center offers 10,000€ scholarships to outstanding mathematics students applying for a master programme in mathematics, for a fist year of Master (M1) or for a second year of Master (M2), in Rennes, Nantes, Angers, Brest or Vannes.

    Eligibility

    The stipend is 10,000 euros per year.

    The M1 scholarships are open to all students who have completed a bachelor's degree in mathematics (or related) at the end of the academic year 2016-2017. The applicants for the Lebesgue M1 scholarship should certify a B1 level of proficiency of the French language.
    A student applying for the first year of a master (M1) will be allowed to apply for another scholarship for the second year (M2).

    The M2 scholarships are open to all students who have completed the first year of a master in mathematics (or related) at the end of the academic year 2016-2017.
    The courses of the second year of Master (M2) may be taught in English.

    The application of the Lebesgue scholarship is independent from the application to Masters programmes, whom modalities are indicated in the dedicated websites.

    Deadlines

    The application for the lebesgue Master Scholarship is open until March 15th, 2018.
    The results of the selection process will be edited in April 2017.

    De très nombreuses situations physiques se modélisent par des systèmes d'équations différentielles. Malheureusement, pour la plupart, on ne sait pas déterminer une solution explicite. Un moyen de contourner cette difficulté est de tenter de calculer une solution approchée. Nous verrons aujourd'hui comment on peut faire cela.

    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.

    Rennes, from February 19th to February 23rd

    Organization board: Xavier Caruso, David Lubicz, Christophe Ritzenthaler, Marie-Françoise Roy

    This workshop will bring together researchers in complex and real algebraic geometry and applied mathematics (physics and cryptography) to discuss numerical methods and open problems on algebraic curves. There will be a number of introductory talks to each of the following topics and invited lectures from specialists: - Theoretical physics/DPE - Computations with the Jacobian - Random real topology - Complexity of computing topology of real algebraic curves - p-adic methods and applications to cryptography
