    4ème Forum Emploi Mathématiques

    Le quatrième Forum Emploi Mathématiques aura lieu le 2 décembre 2014 à Paris (CNAM). Il réunira étudiants en mathématiques (de la licence 3 au doctorat), formations de Master (toutes spécialités au cœur et en interactions avec les mathématiques) et entreprises (ingénieur en R&D, chercheur du monde industriel, privé et académique).
    Le Centre Henri Lebesgue sera présent, aux côtés des formations de master auxquelles il est associé à Rennes et à Nantes.

  • Workshop - Long time dynamics and regularity for hydrodynamical systems
    Mar 11, 2015 to Mar 13, 2015


    Nantes, from March 11th to March 13th

    Organization board: Frédéric Bernicot, Vincent Duchêne

    Although the equations for fluid motion are hundreds of years old, and despite a strong and continuous interest of the scientific community in their study, much remains to be understood. This is not saying that no progress has been made! On the contrary, the study of hydrodynamical systems is a good example of a field where the development of new mathematical tools have accompanied (and sometimes have been developped for) a deeper comprehension of the multiple and complex phenomena hiding behind these seemingly simple sets of equations.

    As for our workshop, the participants will be several of the main contributors to the following topics:

    • Local/Global well-posedness results for (nonlinear) PDEs modeling hydrodynamical systems

    • Local/Global inviscid limit

    • Stability and instability of nonlinear waves

    • Mathematical analysis of free-surface fluids

Conference - Effective moduli spaces and applications to cryptography

Rennes, from June 10th to June 13th, 2014
Contact: D. Lubicz
Organisation board: M. Bolognesi, D. Lubicz, C. Ritzenthaler

Moduli spaces are parameter spaces for mathematical objects equipped (or not) with extra structures. The cases of spaces classifying curves and abelian varieties have been widely studied in their theoretical aspects which entailed dramatic advances in arithmetic geometry. Nonetheless, more effective aspects for instance related to rationality questions or depending on the characteristic of the base field are less well understood. Certain field of applications require tools and algorithms to manipulate efficiently these moduli spaces. This is case for instance of public key cryptography since certain cryptosystems have public parameters which naturally live inside certain moduli spaces.

This conference aims at gathering specialists of moduli spaces of curves and abelian varieties, algorithmic and cryptography so as to explore the deep link and the possible interactions between theoretical and practical aspects of moduli spaces.
