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.

The aim of this workshop on "Magnetic fields and semi-classical analysis" is to present the latest advances, and their applications, in the study of partial differential equations with magnetic fields and semiclassical analysis. This will allow for the interaction between different research communities and stimulate new investigations on a large spectrum of recent problems, from superconductivity theory to Maxwell equation, via spectral theory and dynamics for the Schrödinger equation, and their geometric aspects.

Workshop - Mathematical problems in kinetic theory
Organization board: Anaïs Crestetto, Mohammed Lemou, Florian Mehats
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
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.

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,
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 will open very soon. The scientific program will start on
Monday June 1st at around 4pm and end on Friday June 5th at noon.

Summer schools - Gravity driven flows and environmental risks
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.

Summer schools - Normal forms and large time behavior for nonlinear PDE
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.
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
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).

Piecewise Deterministic Markov Processes are non-diffusive stochastic processes which occur naturally in many different models: communication networks, neuronal function, growth of bacterial populations and reliability of complex systems. The main subjects of study relate to the problems of estimation, simulation and asymptotic behaviors (long time, large populations, multi-scale problems) in different application contexts.
