• Summer schools - Normal forms and large time behavior for nonlinear PDE
    Jun 22, 2015 to Jul 3, 2015

    Registrations closed.

    Place and period

    This summer school will take place at the Faculté des Sciences et Techniques, Université de Nantes, from June, 22nd to July, 3rd, 2015. The organization committee is the following : Erwan Faou, Benoît Grébert, Eric Paturel

    Presentation of the field

    If normal forms were initially used in a finite dimensional setting, for a better understanding of the long time behavior of dynamical systems, their extension to partial differential equations, especially in the nonlinear case, have led to important progresses during this last decade. More than useful tools, they put in light some characteristic phenomena in complex situations where nonlinearity play a fondamental rôle. The aim of this summer school is to show their great adaptability in various fields (Hamiltonian PDEs, fluid mechanics, numerical analysis), and to explain how it works, in a manner accessible to starting researchers.

    Financial support

    Since our summer school is largely devoted to young researchers, we will provide a important number of financial supports. If you asked for a financial support, normally the answer has been sent to you. This support concerns the accomodation during the Summer School (from Sunday evening, June 21st) and the meals (from Monday to Friday, for the two weeks).

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.
