First announcement Progress in Dynamics November 23-27, 2009 Institut Henri Poincaré, Paris The scope of the conference will be wide, but it will emphasize specific problems in dynamical systems, smooth ergodic theory, and related topics, including differential geometry, group theory and number theory, to name a few, that have seen much progress, but where significant problems vital to the field remain open. Specific examples are the Katok entropy rigidity conjecture for geodesic flows of negatively curved manifolds, the Boltzmann ergodic hypothesis, Liouvillean phenomena, the construction of metrics with ergodic geodesic flow, smooth rigidity of actions of abelian groups of higher rank. We will honor Anatole Katok on the occasion of his 65th birthday. The conference will act as a catalyst for research in mathematics and its applications, providing a venue for established scholars to interact - not only with each other, but also with the junior scholars that will play an essential role now and in the years to come. Accordingly, there will be an emphasis on involving young mathematicians in dynamical systems. Limited support for participants is expected to be available. Recent recipients of doctoral degrees, women, and members of traditionally underrepresented groups are particularly encouraged to apply.
