    The position is open to all research areas present within the four Institutes. It does not include an obligation to teach.

    The net salary will be 2 100 Euros per month.


    The application is open.

    Sending application: between the 1st of November 2016 and the 31st of January 2017.

    The 12-month positions are expected to begin on September 1st or October 1st, 2017.


    Candidates must have completed a PhD in mathematics, or equivalent, at the date of taking office. The candidate must submit an original research project including a collaboration with one or more local researcher (s) of Irmar, LMJL,LMBA, or LAREMA.

    Applicants must complete the online form where they have to join the following documents:

    • CV describing the candidate's profile and professional experience (list of publications, research topics, activities)
    • Cover letter including the research project
    • At least two letters of recommendation, including one from the local researcher involved in the project
    (these letters can be uploaded by the applicant or directly sent by the recommending persons at the email address indicated in the second page of the online form)


    The selection is carried by the Lebesgue Scientific Committee.



  • Lebesgue Master Scholarship
    Nov 15, 2016 to Mar 15, 2017
    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 can obtain more information about the masters programmes on the page: Information.


    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.

    De l'oscillateur harmonique quantique

    Ce fut un moment d'enthousiasme et de grande perplexité lorsqu'on découvrit, au début du siècle dernier, que les énergies accessibles de certains systèmes quantiques formaient un ensemble discret. Dans cet exposé, j'en expliquerai la raison mathématique sur l'exemple du célèbre oscillateur harmonique.

    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.

    • Dimitri Zvonkine, University Pierre et Marie Curie

  • Conference - Infinite measure Dynamics
    Jun 6, 2017 to Jun 9, 2017

    Brest, from June 6th to June 9th

    Organization board: Yves Coudène, François Maucourant, Françoise Pène, Barbara Schapira, Samuel Tapie

    Scientific board: Jon Aaronson, Jean-Pierre Conze, Gilles Courtois, Domokos Szasz

    This conference will focus on dynamical systems which naturally preserve a measure with infinite mass. These systems appear in a geometric or probabilistic context, or may come from natural sciences. When the invariant measure has infinite mass, recurrence is no longer automatic, usual mixing properties disappear and new asymptotical properties (such as rationnal ergodicity) may occur. Such systems may develop various and subtil behaviours, which could not exists in finite measure dynamics.

    This conference will gather international experts on this topic, and will allow young researcher to have an easy access to the large recent developpment on such questions.

Frédéric Hélein, Les problématiques de l'édition scientifique

Comment fonctionne la publication des travaux scientifique ? Quel est le rôle des mathématiciens, des bibliothèques et des éditeurs dans ce processus ? Quels sont les rapports de force entre eux ? Quel est l'impact de l'avénement du tout-numérique ? Cet exposé donne quelques pistes pour répondre à ces questions.
