• Semaine d'étude Maths-Entreprises
    May 18, 2015 to May 22, 2015

    Le principe des Semaines d'Etude Maths Entreprises (SEME) est de permettre aux jeunes chercheurs (doctorants et post-doctorants) de travailler par petits groupes, dans un temps limité, sur des sujets proposés par des entreprises.

    Le premier jour est consacré à l'exposé des sujets et à la répartition des groupes ; le dernier jour, les étudiants exposent les pistes explorées pour résoudre le problème posé. Un rapport est ensuite rédigé par les étudiants et publié dans une collection HAL. Pendant la semaine, des tuteurs universitaires et de l'entreprise suivent le travail des étudiants en leur laissant le maximum d'autonomie.

    La SEME du 18 au 22 mai 2015 a lieu au LMJL à Nantes. Les journées de présentation des problèmes (lundi 18 mai 2015) et des travaux (vendredi 22 mai 2015) sont ouvertes à tous.

    Cette semaine est co-organisées par l'AMIES, le LMJL laboratoire d'accueil et le Centre Henri Lebesgue, qui travaillent ensemble pour proposer des sujets, accueillir les étudiants, diffuser leurs résultats et assurer le suivi des interactions entre chercheurs et entreprises initiées à cette occasion.

  • Workshop - Mathematical problems in kinetic theory
    May 26, 2015 to May 29, 2015

    Rennes, from May 26th to May 29th

    Organization board: Anaïs Crestetto, Mohammed Lemou, Florian Méhats

    Kinetic theory is an important field of research that focuses the efforts of re-known international groups coming from various scientific communities. Signifiant advances has been achieved in the last decades, covering mathematical, computational and modeling aspects, but many challenging problems still remain unsolved in this area. Application fields of kinetic theory are numerous: gases dynamics, plasmas and fusion problems, astrophysics and celestial dynamics, population dynamics, biology and cellular activity, socioeconomics and finance, etc. From the modeling point of view, the kinetic models can be thought as intermediate descriptions between fluid models (often insufficient) and particles models (too costly for a practical use). Kinetic systems are in general described by a distribution function depending on time and space but also on additional variables (velocity, character, size, etc). Most of the known kinetic models are given by equations of Boltzmann type, that may be coupled to Maxwell equations. The complexity of these models and the diversity of their structures provide a huge and extremely rich area of research for mathematical analysis, modeling and numerical simulation.

    This workshop aims to present recent developments of mathematical research on the understanding of kinetic models. It will be an opportunity to bring together internationally re-known researchers and young researchers in this domain, in order to exchange the different point of views and to promote the emergence of innovative ideas.

    Several questions will be investigated, including: large time behavior of kinetic equations, formal and rigorous links with N-particles systems, the development of numerical strategies that are suitable for computer simulations, as well as important modeling aspects in various application fields. Open problems will be discussed as well as new applications and research directions.

  • Summer schools - Gravity driven flows and environmental risks
    Jun 1, 2015 to Jun 4, 2015

    Piriac-sur-Mer, from June 1st to June 4th

    Organization board: Christophe Berthon, Benjamin Boutin, Anaïs Crestetto, Carine Lucas, Hélène Mathis

    Scientific board: Christophe Ancey, François Bouchut, Frédéric Coquel, Stéphane Cordier, Josselin Garnier, Sebastian Noelle, Randall J. LeVeque, Carlos Pares, Jacques Sainte-Marie, Stéphane Zaleski

    The prevention of natural risks, the management of water resources and the impact of flows on structures and grounds are essential socio-economics questions nowadays. The modeling and the development of reliable and efficient numerical methods is mandatory to understand such problems. The interdisciplinary GdR EGRIN aims to gather researchers around these topics in order to enforce collaborations.

    This meeting is the third EGRIN school. Informations about the GdR and previous editions are available here.






    A call for contributions will be launched in March 2015.

  • Meeting - Journées EDP

    Roscoff, from June 1st to June 5th

    Organization board: Jean-François Coulombel, Frédéric Rousset

    Scientific board: Nalini Anantharaman, Dario Bambusi, Nicolas Burq, Piero D’Ancona, Nils Dencker, Isabelle Gallagher, David Lannes, Gilles Lebeau, Laure Saint-Raymond, Luis Vega

    The Journées EDP were created in the seventies and have been organized every year since. They have taken place in Saint-Jean-de-Monts, Forges-Les- Eaux, Evian and Biarritz before being currently organized in Roscoff. The topic of the conference is analysis of partial differential equations in a very broad sense: theoretical progress in PDE theory, interactions with other mathematical fields (probability, harmonic analysis, Riemannian geometry...), and interactions with other sciences (fluid mechanics, quantum mechanics, optics, acoustics, biology...).

    The conference consists of one mini-course on recent deep results in the field of partial differential equations, and of a series of talks given both by world leading experts and young researchers.

    The proceedings of the previous Journées EDP are freely available online on the CEDRAM website.

    Registration is open until Monday May 4th. The scientific program will start on Monday June 1st at around 4pm and end on Friday June 5th at noon.

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

    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. This support will cover local accomodation and lunches.

    If you asked for a financial support, you will have the answer in April, 2015.

  • Workshop - Multiscale numerical methods for differential equations
    Aug 25, 2015 to Aug 27, 2015

    Rennes, from August 25th to August 27th

    Organization board: Benjamin Boutin, Philippe Chartier, Nicolas Crouseilles

    Many mathematical models are concerned with physical phenomena occuring at various scales. An efficient numerical solution of such problems requires a specific approach : the severe constraint implied by the smallest scale present in the system would otherwise lead to a prohibitive computational cost. This type of problems appears in various applications such as plasma fusion, multi-fluids flows, or phases transitions.

    The mathematical analysis of these methods and of their extension to similar situations represent a very active domain of research nowadays.

    In particular, an important challenge consists in mimicking at the discrete level certain inherent qualitative properties of the continuous model, such as the preservation of invariants for instance, or the symplecticity of the system. In this spirit, numerous works have been successly undertaken within the framework of Ordinary Differential Equations (ODEs) and have led to the development of efficient numerical techniques. However, their extension to Partial Differential Equations (PDEs) remains incomplete. One of the main objective of this workshop is thus to facilitate the emergence of new ideas and synergies at the frontier of two domains (ODEs and PDEs).
