*Organization board*: Baptiste Chantraine, Vincent Colin, Paolo Ghiggini*Scientific board*: Jean-François Barraud, Baptiste Chantraine, Kai Cieliebak, Tobias Ekholm - School - Flows and Limits in Kähler GeometryApr 18, 2017 to Apr 22, 2017
Nantes, from April 18th to April 22nd

*Organization board*: Sébastien Boucksom, Yann Rollin, Carl Tipler*Scientific board*: Claudio Arezzo, Olivier Biquard, Paul Gauduchon, Michael SingerKähler 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 SymmetryApr 24, 2017 to Apr 28, 2017
Angers, from April 24th to April 28th

*Organization board*: Frédéric Mangolte, Etienne Mann, Laurent MeerssemanTeichmüller 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 DynamicsJun 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 SzaszThis 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 of algebraic transformationsJun 12, 2017 to Jun 16, 2017
Rennes, from June 12th to June 16th

*Organization board*: Serge Cantat, Christophe Dupont - Conference - Random walks on algebraic structuresJun 19, 2017 to Jun 23, 2017
Rennes, from June 19th to June 23rd

*Organization board*: Bachir Bekka, Nizar Demni - Conference - Dynamics on representation varietiesJun 26, 2017 to Jun 30, 2017
Rennes, from June 26th to June 30th

*Organization board*: Ian Biringer, Ludovic Marquis, Juan Souto*Scientific board*: Uri Bader, Jeffrey F. Brock, Jean-Marc SchlenkerNumerous 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.
