    Prochain exposé:

    28-06-2016:  Sébastien Gouezel
    Boltzmann, Birkhoff, Billards

    Résumé :
    On discutera comment la physique statistique inventée par Boltzmann et les rebonds des balles de billards entre elles ont mené à des questions mathématiques délicates d'ergodicité, qui n'ont été résolues que très récemment.

    28-06-2016:  Yves Meyer
    Le rôle des mathématiques dans la détection des ondes gravitationnelles

    Résumé : L'algorithme qui a permis la détection des ondes gravitationnelles le 14 septembre 2015 a été élaboré par Sergey Klimenko (University of Florida). Il utilise de façon essentielle les travaux de Stéphane Jaffard sur les analyses temps-fréquence.

    Battages de cartes, ou comment devenir riche grâce aux maths

    Résumé:
    Combien de fois faut-il battre un jeu de cartes ? La réponse mathématique à cette question fut donnée en 1990 dans un article repris, chose rare, par The New York Times. On propose de parcourir quelques idées clés de cette réponse, le temps d'un voyage express qui reliera les probabilités, l'algèbre linéaire, la théorie des représentations et l'algèbre homologique.

    Permutations dans les séries

    Résumé:
    Quelles sommes peut-on obtenir lorsque l'on s'autorise à modifier l'ordre des termes dans une série ? Nous expliquerons sur ce thème un théorème dû à Lévy (1905) et Steinitz (1913).

  • Conference - 31st International Workshop on Statistical Modelling
    Jul 4, 2016 to Jul 8, 2016

    Rennes, from July 4th to July 8th

    Organization board: Pierrette Chagneau, Jean-François Dupuy, Martine Fixot, Julie Josse, Nathalie Krell, James Ledoux, Laurent Rouvière, Myriam Vimond

    Welcome to the webpage of the 31st International Workshop on Statistical Modelling (IWSM).

    The 31st edition of the IWSM will be held in Rennes (France) from 4 to 8 July 2016, hosted by the Institut National des Sciences Appliquées.

    IWSM is one of the major activities of the Statistical Modelling Society, founded with the purpose of promoting and encouraging statistical modelling in its widest sense, involving both academic and professional statisticians and data analysts. Since its first edition, the spirit of the workshop has always been to focus on problems motivated by real life data and on solutions that make novel contributions to the subject.

    The atmosphere of the workshop is friendly and supportive, with no parallel sessions, with the aim of stimulating the exchange of ideas and experiences related to statistical modelling. As a sign of positive feedback the IWSMs report many returning participants.

    Papers focusing on applications with important substantive implications as well as methodological issues are welcome. Submissions by students and young researchers are particularly encouraged.

    New information about the 31st IWSM will be continuously added on this website. If you have any questions or comments, please contact us.

    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.

  • Conference - Teichmüller Theory in Higher Dimension and Mirror Symmetry

    Angers, from April 24th to April 28th

    Organization board: Frédéric Mangolte, Etienne Mann, Laurent Meersseman

    Teichmüller theory and mirror symmetry are very active domains. In this conference, we propose two series of lectures by two world leaders :

    • Misha Verbitsky on Teichmüller theory
    • Hirochi Iritani on mirror symmetry

    Both will gave each morning an one hour lecture followed in the afternoon by more advanced results by internationnal mathematicians. The goal of this conference is to bring together matematicians from different backgrounds and also to give an overview of the subjetcs to young PhD and post-doc students.

    Lecturers:

    • Hiroshi Iritani, Kyoto University
    • Misha Verbitsky, HSE Moscow

    Speakers:

    • Gaetan Borot, Max Planck Institut, Bonn
    • Fabrizio Catanese, University of Bayreuth
    • Amerik Ekaterina, University of Orsay
    • Maxim Kontsevich, IHES (tbc)
    • Thomas Reichelt, University of Heidelberg

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

    QR-Code

    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.

Workshop - Statistical methods for dynamical stochastic models - DYNSTOCH 2016

Rennes, from June 8th to June 10th

Organization board: Michael Sorensen, Dominique Dehay, Ronan Le Guével

Scientific board: Reinhard Höpfner, Adeline Leclercq Samson, Michael Sorensen, Masayuki Uchida, Dominique Dehay

The DYNSTOCH network is an international network of researchers on various topics in the inference for stochastic processes. The aim is to bring major contributions to this thema using the tools of modern probability theory including stochastic calculous as well as intensive scientific computing methods.

The focus is on estimation, testing and prediction methods for complex dynamic models such as e.g. diffusions, branching processes ... The problems of interest are for example in modeling and data analysis in finance, turbulence, neuroscience, telecommunication networks, hydrology, and other complex technological systems.

The DYNSTOCH 2016 workshop held from Wednesday, June 8th to Friday, June 10th at University Rennes 2 (Campus Villejean, Rennes, France), at the building B, in the amphi B5 Feuillerat.

The slides of the talks are provided in the program page.
