• 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.

  • Meeting - Journées EDP
    Jun 1, 2015 to Jun 5, 2015

    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 now closed. The scientific program will start on Monday June 1st at around 4pm and end on Friday June 5th at noon.

  • Mini-cours "Classical and quantum integrable systems"
    Jun 18, 2015 to Jun 19, 2015

    Álvaro Pelayo, from de l'University of California, San Diego, is the guest of the Lebesgue Center in June 2015. He proposes a 3 hour minicourse outlining recent developments on the symplectic geometry and spectral theory of finite dimensional integrable Hamiltonian systems. There will be an emphasis on the so called toric and semitoric integrable systems.

    Ce mini-cours aura lieu en deux séances, salle 004 (Bat. 22-23 du campus de Beaulieu) - Jeudi 18 juin, 16h-17h30 - Vendredi 19 juin, 10h-11h30

  • 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).

  • 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).

How to come to the conference place

The conference will take place in building 32 B on Beaulieu Campus (campus map).

From the Adagio hotel: take bus n°31 (direction "Beaulieu Chimie") from the stop "Hôtel Dieu" to the stop "Beaulieu Cité U" . You then have to walk to building 32 B (see the map below).

From Résidence universitaire [...] (see the map below).

From the railway station, take the subway (direction J.F. Kennedy) and stop at "Republique". You can then take bus n°4 or n°40 Ex [...]. You then have to walk to building 32 B (see the map below).
