CONFERENCE
Surfaces in Luminy
October 3 - 7, 2016

The study of dynamical systems on surfaces goes back to Poincaré and Birkhoff, with motivations from celestial mechanics. Here are three examples of recent lines of research:
(1) The rotation set was introduced in the 80's; numerous results were obtained recently that reveal the links between the rotation set and the dynamical structure;
(2) The realisation of the Zimmer conjecture on surfaces, by Polterovich and Franks-Handel, has drawn attention of researchers on group actions on surfaces;
(3) The Arnol'd conjecture, which generalizes the famous Poincaré-Birkhoff theorem, has motivated the development of Floer homology in symplectic geometry; on surfaces, this leads to a fruitful dialogue between the symplectic and topological concepts.

The developement of topological tools also allows to describe the dynamics from a global viewpoint, and are also fruitful for studying differentiable systems
Dynamics on surfaces are represented in South America, the United States, Japan, France, Germany, ... This conference will give the opportunity to share the latest advances and the new methods of the subject. It is a natural sequel to Surfaces in Montevideo (2012) and Surfaces in Sao Paulo (2014).

Mini-courses
  • Bertrand Deroin (ENS-Paris)
The ergodic theory of groups of diffeomorphisms of the circle

Abstract: We will review some recent advances and open problems, on the dynamical theory of groups of diffeomorphisms of the circle.  We will more precisely study the relation between the ergodic and topological properties of the action.

  • Patrice Le Calvez (Institut de Mathématiques de Jussieu) & Fabio Tal (University of São Paulo)
Forcing theory for transverse trajectories of surface homeomorphisms

Abstract: Several recent papers on surface dynamics have used transverse foliations and maximal isotopies for homeomorphisms isotopic to the identity as a main tool in their work. In this mini-course we will introduce the basic concepts behind this tool and show a new way o deriving useful dynamical information by means of a forcing procedure. The applications involve ways of obtaining existence of non-contractible periodic points with consequences for rotation sets of toral homeomorphisms, exponential growth of periodic orbits and estimates on topological entropy of maps.
