Description

This workshop is to be held at the International House on the UC Berkeley campus, at 2299 Piedmont Avenue. On site registration for the workshop will be at the International House. The core theme of this workshop is that of the probabilistic approach to the study of partial differential equations, following ideas and work of Henry McKean over five decades, as it has evolved and is sustained in contemporary research. Emphasis will be on six main themes which will be interlaced throughout the program, reflecting the central unity of the approaches to the underlying problems. In this way, researchers whose work is concentrated in one or another of these areas will be exposed to the main threads of the other areas. For each theme we have identified a main speaker who will provide an initial overview. There are six additional themes which are to be touched upon at this workshop. The six main areas and their main speakers are:

1. Random Walks and Singular Diffusions,Charles Newman
2. Strange attractors in periodically forced systems undergoing Hopf bifurcations, Lai-Sang Young
3. Invariant Measures for Nonlinear Partial Differential Equations, Bjorn Birnir
4. Hamiltonian formalism for integrable systems and Riemann surfaces, Kirill Vaninsky
5. Camassa-Holm Equation, Euler-Poincare and Geodesic Flows on the Diffeomorphism Group, Darryl Holm
6. Random Navier-Stokes Systems, Jonathan Mattingly
