    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.


    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.


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

    Applicants must complete the online form and attach the documents:
    - CV
    - Transcripts
    - Cover letter
    - One or more letters of recommendation.

    Applicants must submit the application only when it is complete. Only electronic submission using the online form will be considered.


    The selection will be carried out by the Lebesgue Scientific Committee and the heads of the Masters programmes. It will be based on the academic quality of the applicant.

  • School - Masterclass
    Dec 13, 2016 to Dec 15, 2016


    Angers, from December 13th to December 15th

    Organization board: Etienne Mann, Loïc Chaumont

    We organize a Masterclass in Angers from the 13rd to 15th December. Lectures will be in the morning sessions and exercises session will take place in the afternoon. We will have two parallel sessions:

    • Laurent Evain : The Hilbert scheme.
      The programm is grassmannian varieties, Hilbert scheme and some applications.
    • Rodolphe Garbit: Counting paths in an orthant: a probabilistic approach
      The lectures will focus on Brownian motion, random walks and their application to some combinatorial problems.

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

  • School - Flows and Limits in Kähler Geometry
    Apr 18, 2017 to Apr 22, 2017


    Nantes, from April 18th to April 22nd

    Organization board: Sébastien Boucksom, Yann Rollin, Carl Tipler

    Scientific board: Claudio Arezzo, Olivier Biquard, Paul Gauduchon, Michael Singer

    Kähler geometry is a very active research field, at the crossroads between algebraic and Riemannian geometry. Important breakthrough, that lead to solve the Yau-Tian-Donaldson conjecture in the Fano case, have been achieved recently. A spring school involving mini-lectures and talks around this thread of new ideas in Kähler geometry is organized at Nantes University. The goal of the school is to develop certain technical skills, useful to address a variety of important questions in algebraic geometry and global analysis on manifolds, aimed for PhD students and young researchers. Geometric flows, like the Kähler-Ricci flow for instance, and the associated quantification by the Donaldson dynamical system, will be among the essential tools dealt with during the school.

Practical information for the meeting WS3

How to come to Rennes

If you arrive in Paris either by plane or train, the simplest is to use the french high-speed train (TGV) to go to Rennes (2h15' from Montparnasse station, 3h from the Airport station).

For those landing at Charles-de-Gaulle airport, you may also use a connecting flight to Rennes.

How to reach your accomodation place

To go to the Adagio hotel from the railway station: take the subway (direction J.F. Kennedy) from station "Gares" to station "Saint-Anne", and then walk on "rue d'Antrain" street (see the map below) from "Place Saint-Anne" to the hotel.

To go to Résidence universitaire from the railway station: take bus n°1 (direction Cesson-Sévigné) from stop "Gares" to stop "Mirabeau". Then walk down to builiding D (see the map below).

How to come to the conference place

The conference will take place in amphitheater N of ESIR building (ESIR=école supérieure d'ingénieurs de Rennes) on Beaulieu Campus (campus map).

From the Adagio hotel: take bus n°31 (direction "Beaulieu Chimie") from the stop "Hôtel Dieu" to the stop "Beaulieu Chimie" . You then have to walk to ESIR building (see the map below).

From Résidence universitaire: you can walk to ESIR building (see the map below).

From the railway station: take the subway (direction J.F. Kennedy) and stop at "Republique". Then take bus n°4 (direction Beaulieu Atalante) and stop at "Beaulieu Chimie". You then have to walk to ESIR building (see the map below).

Timetables, PDF maps of the bus lines are available on the Star website (only in french sorry).

Annotated map

You will find information on the conference place, bus stops, restaurants etc. on the annotated map below.
