Mathematical research on resonance oscillations in nonsmooth systems has seen a steady growth in attention lately, and due to recent progress a number of technically relevant open problems concerning resonances of nonsmooth mechanical and physical systems have become in reach of being resolved. The object of the meeting is to explore the current power and open problems of the theory of resonance oscillations and stability of nonsmooth systems (Lipschitz, discontinuous, impulsive) by bringing together different research groups working in the field as well as by organizing discussions with relevant industrial experts. The first part of the workshop (four days: 16-19 June) will be formal, with a full schedule of invited and contributed talks. In contrast, the 2nd part (four days: 22-25 June) will be more informal, with discussion sessions on specific problems aimed at developing new research collaborations.

The conference will include topics such as real and holomorphic one- and two-dimensional dynamics, conservative low-dimensional dynamics, and the Teichmüller flow.

Misha Lyubich mlyubich@math.sunysb.edu
Marco Martens marco@math.sunysb.edu
John Milnor jack@math.sunysb.edu

The conference will be devoted to the interaction between various branches of Mathematical Analysis. The main themes will be Complex Dynamical Systems and Loewner Equations, Geometric Function Theory, Hyperbolic Geometry, Partial Differential Equations, Pseudodifferential Operators, Differential Geometry, General Relativity and Einstein Equations.

We intend to publish the Proceeding of the Conference in the AMS Contemporary Mathematics Series.

The purpose of this conference is to bring together mathematicians working on different aspects of ergodic theory. The main topics are:

* entropy and classification;
* smooth models;
* rigidity phenomena in ergodic theory;
* interaction with combinatorics and number theory;
* convergence and recurrence theorems;
* nilpotent ergodic theory.

We will also use the opportunity to honor Jean-Paul Thouvenot, who has recently retired from CNRS, and his major contributions to the development of French ergodic theory.

The conference is partially supported by grants from the NSF and several French universities.
