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
Organization board: Yves Coudène, François Maucourant, Françoise Pène, Barbara Schapira, Samuel Tapie, Annick Nicolle
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 - Families of algebraic dynamical systems
Scientific board: Bachir Bekka, Emmanuel Breuillard, Nizar Demni, Alex Lubotzky
The conference deals with themes around random walks on algebraic structures.
Dynamical sytems on groups, homogeneous spaces, and related structures (graphs, quantum groups , groupoids,...) are rich objects, involving various fields of mathematics (probability, group theory, topology, number theory, operator algebras, Banach space geometry, etc). They are also useful as modelling tools for other sciences (physics, computer science, economics, etc); for instance, expander graphs, which are of interest in theoretical computer science, are graphs for which the associated random walk has special spectral properties and their explicit construction involves sophisticated tools such as Kazhdan's property (T) or Selberg's inequality.
The conference aims to give a flavor of the various aspects of the subject by bringing together some experts with major contributions to the field.
This conference will also be the opportunity to celebrate the 80th birthday of Yves Guivarc'h, who played a major part
in the development of probability on algebraic and geometric structures, a subject with an ever growing interest for the last 30 years.

The map of the campus of the school of Science and Technology: The math building is marked # 10.
You may use this interactive map to follow the directions below.
From the train station (follow the blue path):
Upon your arrival at the main station ("La Gare"), take the north exit ("Sortie nord") and follow the direction to the tramway stop, (Line #1, La Gare) in front of the main entrance of the station. Take the tramway in the direction of "François Mitterrand". Get off the car at "Place du Commerce" and take the tramway line # 2 in the direction of "Orvault-Grand Val". Get off at "Michelet Sciences", enter the campus and walk to the math buliding following the red path in the map above. You may use the campus map provided above.
The cost of an one-hour-valid ticket is 1,20 Euros and there are some vending machines at each stop.
Attention: The vending machines may not take non-France issued credit/Banking cards. Almost certainly, they will not take a US issued credit/ATM cards.__
For detailed bus and tramway schedules please visit TAN.
You can get to the city center by the airport shuttle bus (TAN AIR Shuttle) in 20 minutes. The final stop of the shuttle is "Place du Commerce" and there is one bus every 30 minutes. From there you can take the tramway Line #2 in the direction of "Orvault Grand Val" and get off at "Michelet Sciences". Follow the red path to the institute.
At the main entrance of the Hall 4 you will find a taxi shelter where you can call for a taxi to pick you up.
