  • Rencontres Doctorales Lebesgue 2015
    Oct 28, 2015 to Oct 31, 2015

    Dates : du 28 au 30 octobre 2015
    Location : UFR Sciences et Techniques Amphithéâtre Pasteur, Nantes

    Comité d’organisation : Adrien Fontaine (Rennes), Olivier Pierre (Nantes), Victor Vilaça Da Rocha (Nantes), Thomas Wallez (Nantes).

    Comité scientifique : Thomas Beaudouin (Nantes), Johan Leray (Angers), Noémie Legout (Nantes), Axel Rogue (Rennes).


    Objectif

    Le but de ces rencontres est de présenter un panorama de la recherche mathématique à travers les exposés de doctorants d’horizons géographiques et mathématiques variés ainsi que de trois chercheurs parrains de cet événement.

    Bien que principalement orientée vers les doctorants, cette conférence se veut également accessible aux étudiants de M2 désireux d’avoir un aperçu des travaux auxquels une thèse en mathématiques peut mener. Ces rencontres sont organisées avec le soutien du Centre Henri Lebesgue, du Laboratoire de mathématiques Jean Leray de Nantes, du Laboratoire angevin de recherche en mathématiques, de l’Institut de recherche en mathématique de Rennes et de l'école doctorale STIM.

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

    QR-Code

    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 preceded by two short courses by Hermine Biermé (Poitiers) and by Yongtao Guan (Miami) on two days.

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.
