Proceedings: Markov Processes and Related Fields 14(3) 2008

Tuesday 23 and Wednesday 24 January 2007- Schedule

Amphi Hermite
Institut Henri Poincaré
11, rue Pierre et Marie Curie

The aim of this annual workshop is to bring together mathematicians and physicists working on disordered or random systems, and to discuss recent developments on themes of common interest. Each of the two days is devoted to a specific topic, as described below for the 2007 session.

Tuesday 23 January: Stochastic models of selection and coalescence.
        Moderator: Bernard Derrida (Paris)

The goal of this short meeting is to bring together experts of two fields where noticeable progress has been done over the last decade: on the one hand, the problem of traveling waves in presence of noise, which represent the large scale limit of a variety of stochastic models of the reaction-diffusion type or of evolution in presence of selection; on the other hand, stochastic models of selection leading to fluctuating genealogies, which can be seen as random branching processes. The meeting will try to review some recent results concerning the effect of noise on the position (velocity, diffusion constant) of traveling waves. It will also try to present recent results on fluctuating trees which occur in several contexts, in particular in the theory of spin glasses or in models of evolution in presence of selection.

Preliminary list of Speakers: E. Bolthausen (Zürich), E. Brunet (Paris), D. A. Kessler (Ramat-Gan), J.-F. Le Gall (Paris), E. Moro (Madrid), C. Mueller (Rochester), S. Munier (Palaiseau), F. Yu (Oxford).

Wednesday 24 January: Dynamics and statistics of non-equilibrium phenomena.

        Moderator: Claude-Alain Pillet (Toulon)
Understanding non-equilibrium processes, in particular transport phenomena, in classical and quantum systems remains a challenge: extending basic objects of equilibrium statistical mechanics to non-equilibrium situations leads to conceptual problems and the necessity to control dynamics on a large time scale is a very hard task. We will present some of the most recent developments obtained in the following directions: ergodic theory of classical and quantum Markov processes, stochastic differential equations; effective dynamics, non-equilibrium steady states; linear response theory and beyond; quantum transport in disordered and mesoscopic systems.

Preliminary list of Speakers: Laurent Bruneau (Cergy), François Castella (Rennes), Wojciech De Roeck (Leuven), Davide Gabrielli (L'Aquila), François Germinet (Cergy), Martin Hairer (Warwick), Christian Maes (Leuven).
