    In May 1969 the groundbreaking book of Jean-Marie Souriau appeared, Structure des systèmes dynamiques. We will celebrate, in 2019, the jubilee of its publication, with a conference in honour of the work of this great scientist.

    The influence of Souriau’s work is felt in the areas he has innovated or developed in his own way. It is important to take stock of it, in particular in order to make the current and future generations aware of his original and deep thought.

    The main reasons for organising this conference are the singularity, and at the same time the scope, of the work of Souriau. He was able to create, in his time, a homogeneous group of “Souristes” who for the most part have reached maturity and are able today to convey the originality of this work. It is also time to take stock of the important work to which it has given rise among foreign researchers, many of whom we will invite to speak. The work of Jean-Marie Souriau lives on in different areas of the scientific world and, at different levels of depth, in the development of mathematics and physics, and therefore according to the different temporalities of the history of these disciplines.

    All scholars, old and new, recognize this. Souriau’s work is particularly important work for the relationships he has established and developed between physics and geometry. He is one of the most important founders of symplectic geometry, and the theoretical exploitation of his work in this field is far from exhausted.

    André Lichnerowicz has said that his work could belong to four international scientific unions: mathematics, mechanics, physics and astronomy. But what interests us is not only Souriau the scientist, but also the philosopher. What is striking is the unity of his thought through the variety of his fields of interest. It is likely true that this thought grows deeper as its areas of application expand. The object of our inquiry will be to analyse his thought insofar as it is related to the philosophy of science and even to pure philosophy.

    This conference aims to review the entire work of Jean-Marie Souriau in the five areas in which he worked.

    1. Symplectic mechanics. Symplectic structure of the space of the movements of a dynamic system, action of invariance groups, moment map, symplectic cohomology, barycentric decomposition theorem. Elementary systems (particles): homogeneous symplectic variety, classification by coadjoint orbits.

    2. Geometric Quantization. Prequantization condition, pre-quantum bundle, polarizations, quantification of coadjoint orbits.

    3. Thermodynamics. Geometric statistical equilibria in symplectic manifolds. Vector temperature and thermodynamic dissipative model in general relativity.

    4. General Relativity and Cosmology. General Covariance Principle, Robertson-Walker universe model with cosmological constant.

    5. Diffeology. Renewal of the formal framework of differential geometry by a stable space category by all natural set operations (i.e. complete, complete, Cartesian closed). This includes highly singular spaces that may not even be separated, infinite dimensional spaces, and so on.

    6. Philosophy of Science, Epistemology, History of Science. History of each of the domains evoked (symplectic mechanics, quantification, cosmology and relativity, thermodynamics). In each of these areas Souriau introduced new ideas. These new views have not ceased to be relevant and fruitful. The task of a philosophy of science will be to highlight this novelty.

    As far as philosophy is concerned, a new question has been raised about the importance of this work, in its variety and unity, and in its impact on the philosophy of science and philosophy in general, which we propose to deal with in this conference. Souriau’s originality manifested itself in his will and in his attempts to create new languages. We will analyze, in the philosophy section, this important aspect of his work, most evident in his work in geometry and relativity.

    An overview over recently developed methods for proving decay to equilibrium for dissipative dynamical systems is presented. The methodology is based on Lyapunov functionals, often with the physical interpretation of a (generalized) entropy or free energy.
    The course features a short formal introduction to stochastic processes, aimed at an audience with a PDE background. The concepts of martingales and time reversal of homogeneous Markov processes are used to derive local decay results for relative
    entropies. These are applied to various examples of Levy processes, including applications in kinetic transport theory, in mathematical biology, and in chemical reaction networks. Quantitative decay results are derived from entropyentropy decay inequalities or from inequalities between entropy decay and its time derivative, i.e. by the celebrated Bakry-Emery approach.
    A focus is on hypocoercive problems, where decay to equilibrium holds despite the fact that the decay term for the natural entropy functionals is only semi-denite. Various recent approaches to such problems, mainly in kinetic theory, are compared and unied.
    Finally, examples of nonlinear problems are discussed, and the question of structural assumptions allowing for entropy decay is examined.

    Information about the research
    The Division of Applied Mathematics and Statistics at the Department of Mathematical Sciences at Chalmers University of Technology and the University of Gothenburg, together with the Agrifood and Bioscience unit of RISE Research Institutes of Sweden, invites applications for one two-year postdoctoral position starting November 1, 2018, or as agreed. The successful candidate will be offered a one-year employment at Chalmers, followed by a one-year employment at RISE Agrifood and Bioscience.

    The aim of the project is to develop new tools and methods for statistical modeling of random, heterogeneous, porous material structures. This involves both to work with two- and three-dimensional imaging data of real material structures and with simulation of virtual material structures inspired by real materials to understand the connection between structure and mass transport properties (diffusion and flow). The project constitutes part of a collaboration with several major Swedish industries, as well as with experimentalists in academia, and the methods and software that are developed within the project will be applied to real, industry-relevant materials used in for example hygiene products, packaging materials, pharmaceuticals, etc.

    As part of the VINNExcellence Centre SuMo Biomaterials (SuMo), the project ‘Material structures seen through microscopy and statistics’ funded by the Swedish Foundation for Strategic Research, and the project ‘Mass transport properties of soft porous granular materials’ funded by the Swedish Research Council, many tools for image analysis, statistical characterization, and generation of virtual material structures have been developed. Further, within the SuMo Centre, state-of-the-art software for lattice Boltzmann-based diffusion and flow simulations is available.

    The aim is to build upon the accumulated knowledge from these projects and:

    (1) Develop new image analysis and segmentation algorithms for image data. Highly accurate automatic or semi-automatic image analysis methods are crucial for segmentation of imaging data of material structures. This is particularly important for 3D data where data size makes complete manual segmentation very time-consuming.

    (2) Develop new spatial and spatio-temporal models for fiber materials, foams, granular media, etc, using knowledge acquired through studying real materials.

    (3) Perform simulation studies of mass transport properties using available simulation tools developed in related projects together with new methods of generating material structures. Exploring material structures in the computer is important to avoid costly and time-consuming experimental studies.

    The goal is a deep understanding of the relationships between microstructure and properties that will benefit both further research and applications.

    This position is one of three postdoctoral positions within the new project CoSiMa, which is part of the SuMo Biomaterials centre (

    Conférence-débat de l'Académie des sciences, de 14h30 à 16h45, dans la Grande salle des séances de l’Institut de France - Inscription obligatoire avant le 9 octobre 2018

    Alain Berthoz, professeur honoraire au Collège de France, membre de l'Académie des sciences et de l’Académie des technologies.


    • Neil Burgess, professeur et directeur de l’Institute of Cognitive Neuroscience, University College London, membre de la Royal Society et de l’Academy of Medical Sciences
    • Laure Rondi-Reig, directrice de recherche au CNRS à l’Institut de Biologie Paris–Seine, Université Pierre-et-Marie-Curie
    • Alain Berthoz, professeur honoraire au Collège de France, membre de l'Académie des sciences et de l’Académie des technologies
    • Daniel Bennequin, professeur émérite au département de mathématiques de l’université Paris Diderot.

    Le thème général de cette séance sera d’exposer des découvertes et théories récentes concernant le traitement cérébral de l’espace et plus particulièrement la flexibilité des stratégies cognitives et la diversité des réseaux de traitement des divers espaces d’action.
    Neil Burgess décrira les divers types de neurones de la formation hippocampique qui codent la place, la direction, les bords, leur organisation en grilles et les relations avec les objets. Il décrira un modèle mathématique de transformation entre les divers référentiels spatiaux (égocentré, allocentré etc.) et son utilisation pour prédire des symptômes de déficits de la mémoire spatiale dans des pathologies post-traumatiques.
    Laure Rondi-Reig décrira les réseaux neuronaux impliqués dans des activités de navigation spatiale, l’apprentissage et les troubles de la mémoire, dans le cas du vieillissement par exemple. Des données expérimentales sur les mécanismes neurophysiologiques et la diversité des réseaux corticaux et sous corticaux de la cognition spatiale et des modèles inspirés des neurosciences computationnelles seront présentés.
    Alain Berthoz proposera que le cerveau traite avec des réseaux différents et des géométries différentes pour les divers espaces (corps, préhension, locomoteur, environnemental). Il décrira des données récentes sur les bases neurales des changements de perspective, le développement chez l’enfant des fonctions visuo-spatiales et l’intervention de la manipulation des référentiels spatiaux dans l’empathie et son implication en pathologie psychiatrique.
    Daniel Bennequin proposera que pour guider l’adaptation des actions et des perceptions, les cerveaux des animaux et de l’homme mettent en place une variété de géométries, Euclidiennes et non Euclidiennes, et de dynamiques. L’exposé présentera un travail sur une nouvelle sorte de géométrie : un topos d’espaces au-dessus d’une catégorie (site) représentant la préparation et l’exécution d’une classe de mouvements; par exemple la préhension, la locomotion, la navigation, l’imagination.

    This ICML workshop seeks to broaden the role of geometric models and thinking in machine-learning research.

    The interplay between machine learning and geometry is an active field of research drawing the attention of researchers from many fields as it offers not only beautiful mathematical and statistical theory but also substantial impact on important real-world problems in machine learning. Examples of this interplay include, but are not limited to:

    • geometric insights into deep learning (helping us to better understand and improve these models);
    • statistical models that respect and exploit the constraints of geometric data ("statistics on manifolds");
    • (Riemannian) manifold learning;
    • viewing probability distributions as points on a nonlinear manifold ("information geometry");
    • optimization over nonlinear manifolds;
    • Wasserstein spaces and their applications;
    • understanding the effect of encoding group invariances (e.g. rotation invariance) on the intrinsic geometry of the data space, which becomes a quotient space.

    This ICML workshop is co-located with ICML, IJCAI and AAMAS in Stockholm.

    The Bosch center for AI generously sponsors a prize for the best abstract, which will be presented at the workshop.
