    Kähler geometry is a very active research field, at the crossroads between algebraic and Riemannian geometry. Important breakthrough, that lead to solve the Yau-Tian-Donaldson conjecture in the Fano case, have been achieved recently. A spring school involving mini-lectures and talks around this thread of new ideas in Kähler geometry is organized at Nantes University. The goal of the school is to develop certain technical skills, useful to address a variety of important questions in algebraic geometry and global analysis on manifolds, aimed for PhD students and young researchers. Geometric flows, like the Kähler-Ricci flow for instance, and the associated quantification by the Donaldson dynamical system, will be among the essential tools dealt with during the school.

  • Conference - Teichmüller Theory in Higher Dimension and Mirror Symmetry
    Apr 24, 2017 to Apr 28, 2017

    Angers, from April 24th to April 28th

    Organization board: Frédéric Mangolte, Etienne Mann, Laurent Meersseman

    Teichmüller theory and mirror symmetry are very active domains. In this conference, we propose two series of lectures by two world leaders :

    • Misha Verbitsky on Teichmüller theory
    • Hirochi Iritani on mirror symmetry

    Both will gave each morning an one hour lecture followed in the afternoon by more advanced results by internationnal mathematicians. The goal of this conference is to bring together matematicians from different backgrounds and also to give an overview of the subjetcs to young PhD and post-doc students.

    Lecturers:

    • Hiroshi Iritani, Kyoto University
    • Misha Verbitsky, HSE Moscow

    Speakers:

    • Gaetan Borot, Max Planck Institut, Bonn
    • Fabrizio Catanese, University of Bayreuth
    • Amerik Ekaterina, University of Orsay (tbc)
    • Maxim Kontsevich, IHES (tbc)
    • Thomas Reichelt, University of Heidelberg
    • Claude Sabbah, Ecole polytechnique
    • Andrei Teleman, University of Aix-Marseille
    • Dimitri Zvonkine, University Pierre et Marie Curie
  • Conference - Infinite measure Dynamics
    Jun 6, 2017 to Jun 9, 2017

    Brest, from June 6th to June 9th

    Organization board: Yves Coudène, François Maucourant, Françoise Pène, Barbara Schapira, Samuel Tapie

    Scientific board: Jon Aaronson, Jean-Pierre Conze, Gilles Courtois, Domokos Szasz

    This conference will focus on dynamical systems which naturally preserve a measure with infinite mass. These systems appear in a geometric or probabilistic context, or may come from natural sciences. When the invariant measure has infinite mass, recurrence is no longer automatic, usual mixing properties disappear and new asymptotical properties (such as rationnal ergodicity) may occur. Such systems may develop various and subtil behaviours, which could not exists in finite measure dynamics.

    This conference will gather international experts on this topic, and will allow young researcher to have an easy access to the large recent developpment on such questions.

  • Conference - Dynamics on representation varieties

    Rennes, from June 26th to June 30th

    Organization board: Ian Biringer, Ludovic Marquis, Juan Souto

    Scientific board: Uri Bader, Jeffrey F. Brock, Jean-Marc Schlenker

    Numerous areas of mathematics are touched by what could be called Dynamics on representation varieties. For instance one could mention ergodic theory, Riemannian geometry, low-dimensional topology, Teichmüller theory, and so on... The aim of this workshop is to bring together graduate students, recent graduates and experts in these different areas, giving everybody ample time for discussions and collaborations. Next to a number of research talks, three mini-courses by Tsachik Gelander, Francois Labourie and Julien Marché will take place.

Spring school - Classical and p-adic Hodge theories

Rennes, from May 12th to May 23rd, 2014
Contact: C. Mourougane
Scientific board: X. Caruso, F. Charles, M. Gros, C. Mourougane

We organize a spring school on complex and p-adic aspects of the Hodge theory with a view towards deformation theory.

The first week is devoted to constructions of complex and p-adic Hodge theories, for a single smooth variety or for a smooth family of smooth varieties. In the complex setting, construction of moduli spaces thanks to Torelli type theorems will be the main target. In the p-adic setting, the first aim will be the constructions of cohomological tools and the second aim the statement and the proof in a special case of comparison theorems between p-adic cohomologies.

Hodge theories of deformations with singular fibers will be the topic of the second week. In the complex setting, one leading theme will be the use of Hodge theory in the description of properties of moduli spaces like hyperbolicity. Similarly, some properties of étale cohomologies and more surprisingly complex cohomologies will be derived from p-adic Hodge theory.

Each course will be given in English and divided into three lectures of 90 minutes.
