• Lebesgue Master Scholarship
    Nov 16, 2015 to Mar 10, 2016
    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 2015-2016. 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 2015-2016.
    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 10th, 2016.
    The results of the selection process will be edited in April 2016.


    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.

  • 5 minutes Lebesgue
    Dec 1, 2015

    Le Centre Henri Lebesgue propose une nouvelle série vidéo intitulée "5 minutes Lebesgue". Nos chercheurs proposent des exposés de 5 minutes sur un sujet mathématique de leur choix. Les exposés s'adressent à un public allant du niveau "lycée" à des spécialistes.

    Prochain exposé

    Guillaume Poly, Le problème de l'aiguille de Buffon

    On fait tomber des allumettes sur un parquet dont les lattes sont régulièrement espacées. On va calculer la probabilité qu'une allumette tombe à cheval entre deux lattes.

  • Journées Filles et Maths
    Dec 10, 2015

    Il s'agit d'un temps de réflexion, d'échange, et d'information, destiné à des lycéennes, sur les études et métiers des mathématiques, et les stéréotypes qui freinent souvent les jeunes femmes pour s'orienter vers ces parcours.
    Destinées à encourager les jeunes filles à s'orienter vers des études de mathématiques et plus généralement des études scientifiques et techniques, ces journées sont organisées par les associations Femmes et mathématiques et Animath, depuis fin décembre 2009.

    L'Université de Rennes 1 et le Centre de mathématiques Henri Lebesgue s'associent à cette initiative et organisent le 10 décembre 2015 la prochaine manifestation "Filles et mathématiques : une équation lumineuse !" pour les lycéennes de la région Bretagne.

    Programme de la journée :

    09h30-10h00 : Ouverture autour de jeux mathématiques
    10h00-10h45 : Conférence
    10h45-12h15 : Speed-meeting "Des métiers et des maths"
    12h15-13h30 : Déjeuner
    13h30-14h15 : Ateliers sur les métiers
    14h15-15h45 : Théâtre-forum « Dérivée », pièce de théâtre interactive
    15h45-16h00 : Conclusion de la journée

    La journée est entièrement gratuite : le repas et les petites collations sont à notre charge.

    Modalités d’inscription

    • étape 1 : pré-inscrire vos élèves avant le 30 novembre en remplissant ce formulaire - (cette pré-inscription est réservée aux établissements ayant déjà obtenu l'accord du comité d'organisation):
    • étape 2 : remplir, signer, faire signer et nous renvoyer cette convention:
    • étape 3 : attendre la confirmation de notre part au plus tard le 03 décembre 2015.

  • Conference - Stochastic Geometry
    Apr 4, 2016 to Apr 8, 2016


    Nantes, from April 4th to April 8th

    Organization board: Jean-Christophe Breton, David Coupier, Bernard Delyon, Frédéric Lavancier, Ronan Le Guével, Nathalie Krell, Nicolas Pétrélis, Anne Philippe, Paul Rochet

    In association with the GDR 3477, the Stochastic Geometry days aims at gathering together reseachers investigating from a theoretical or practical viewpoint random spatial models. For this 5th edition, the conference focuses on random geometry, point processes, spatial statistics, spatial stochastic fields, time-space processes.

    The conference will be held from April 6th to April 8th and will be preceded by a school on April 4th and 5th. This school will propose two short courses:

    • Introduction to random fields and scale invariance by Hermine Biermé (Poitiers)

    • Introduction to Spatial Point Pattern Analysis by Yongtao Guan (Miami).

    Registrations are open up to January 31th 2016, in the limit of approximately 70 participants.

  • Conference - Statlearn: Challenging problems in statistical learning

  • Workshop - Workshop on Stochastic Weather Generators
    May 17, 2016 to May 21, 2016


    Vannes, from May 17th to May 21st

    Organization board: Pierre Ailliot, Denis Allard, Anne Cuzol, Ronan Fablet, William Kleiber, Etienne Mémin, Valérie Monbet, Philippe Naveau, Pierre Tandeo, Ying Sun

    How can we reliably predict climate-related risks? Stochastic weather generators give us this ability by simulating sequences of daily weather and climate consistent with specific aspects of climate variability and change. The simulated sequences of meteorological variables (rainfall, wind, temperature,...) are typically used as inputs into complex environmental and ecosystem models. They have a wide range of applications in hydrology, agriculture and environmental management.

    This workshop aims at bringing together a wide range of researchers, practitioners, and graduate students whose work is related to the stochastic modelling of meteorological variables and stochastic weather generators.

    The 11th French-Danish Workshop on Spatial Statistics and Image Analysis in Biology (SSIAB 11) will take place in May 25-27 2016 in Rennes (Brittany) at the French Institute for Research in Computer Science and Automation (Inria). It is jointly organized by the Serpico team of Inria, the Mathematics research institute IRMAR of the University of Rennes 1 and the Inra Institute of Genetics, Environment and Plant Protection (IGEPP). This workshop is devoted to spatial statistics and image analysis and their applications in biology (e.g. agriculture, epidemiology, ecology, health, environment).

    The first edition took place in Garchy (France, March 1996) and the last two editions took place in Aalborg (Denmark, May 2014) and Avignon (France, May 2012) respectively.

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.


Master 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.
