Nipissing University will offer a Workshop on Recent Advances in Topological and Measure-Theoretic Methods in Dynamical Systems in order to bring researchers and students in these areas together for a five-day series of workshops. The workshops will be jointly supported by the National Science Foundation (funding recommended, but final approval pending) and the Fields Institute, and will be held at Nipissing~Rs pleasant campus in North Bay, Ontario, Canada, May 17-21, 2010.

Over the last 30 years, there have been many developments that have increased the interaction among topology, measure theory, and dynamical systems. Pending NSF support will be used for at least 10 US-based students and recent PhDs to attend the workshops. The workshops will provide the opportunity for recently trained professional mathematicians and students to prepare for research in areas in which current developments are moving rapidly at the intersection point of topology, measure theory, and dynamics. Major speakers with international reputations have been selected who are active in these research areas. Please see the website below:

The plan is to bring together people working on different aspects of the dynamics of rational maps on the Riemann sphere. All those interested in this area are encouraged to register. Accommodation for those connected with the CODY Network will be covered by University of Warwick node.

Organizers: Davoud Cheraghi, Sebastian van Strien.

The school will focus on the study of periodic approximations as a tool to understand the ergodic properties of deterministic dynamical systems, and as a method of construction of examples (and counter-examples) of ergodic behavior, especially in dynamics related to quasi-periodic motion, such as perturbations of completely integrable systems, KAM theory, Arnol'd diffusion theory, quasi-periodic cocycles, Schrodinger equation, 1-dimensional complex dynamics around elliptic fixed points, etc.

The school will be aimed at students and young researchers and its goal is to provide them with the state of the art ideas and techniques of the included topics.

Organizers : Carlo Carminati (Pisa), Bassam Fayad (Paris 13), Anatole Katok (PSU), Raphael Krikorian (Paris 6), Stefano Marmi (Pisa).

Scientific committee : Hakan Eliasson (IMJ Paris), Giovanni Forni (Maryland University), Antonio Giorgilli (Milano), Jean-Christophe Yoccoz (College de France Paris).

The courses :

1) Periodic approximation in measurbale dynamics and surface homeomorphisms : Frederic Leroux (Orsay Univesity Paris).

2) Fast periodic approximations and constructions by successive conjugations. Bassam Fayad (Paris 13) and Anatole Katok (PSU).

3) Quasi-peridoic cocycles with Liuovillean frequencies. Raphael Krikorian (Paris 6) and Jairo Bochi (PUC Rio de Janeiro).

4) Julia sets with positive measure. Xavier Buff (Toulouse) and Arnaud Cheritat (Toulouse).

To register, participants are kindly requested to fill the on-line form : http://tinyurl.com/ygnft8o

and mention whether they will need financial support. It is important to note that the deadline for registrations asking for financial support is December 1st 2009, while registration without financial support requested is open until December 15.

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 65^th

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.
