INHOMOGENEOUS RANDOM SYSTEMS Systèmes Aléatoires Inhomogènes Tuesday 24 and Wednesday 25 January 2006 Amphi Hermite Institut Henri Poincaré 11, rue Pierre et Marie Curie Paris

The aim of this annual workshop is to bring together mathematicians and physicists working on extended random systems, and to discuss recent developments on themes of common interest. Time does not allow for oral communications other than the invited lectures. The `` Rencontre de Physique Statistique'' taking place in Paris 26 and 27 January 2006 welcomes short communications.

The 2006 session will be devoted to:

Moderator: Wendelin Werner (Orsay)

The Stochastic Loewner Evolution has improved the understanding of the critical behavior of two-dimensional systems from statistical physics. This has given rise to numerous work both from mathematicians and theoretical physicists on this subject, that had already received a lot of attention in the theoretical physics community since the early eighties (conformal field theory, Coulomb gas methods, quantum gravity, etc.). The purpose of this day is to bring together mathematicians and physicists working on these themes to hear about recent advances and ideas in this field.

List of speakers: M. Bauer (Saclay), V. Beffara (Lyon), F. Camia (Amsterdam), J. Cardy (Oxford), J. Jacobsen (Orsay), S. Smirnov (Genève & Stockholm), J.A. Trujillo Ferreras (Zürich).

Moderator: Herbert Spohn (München)

The statistical mechanics of a polymer chain without geometric constraints is isomorphic to a random walk. Lots of efforts have been invested to understand the effect of a repulsive interaction between monomers. However, there is another direction, loosely summarized as "random polymer". Random polymers are mostly concerned with ideal polymers. They may have an internal structure, like the copolymer "...ABAB...", and they are immersed in a more structured environment. For example a copolymer could be located at an interface of two fluids, where one of them prefers monomer A and the other monomer B. Or, in case of an ideal polymer, the environment could have random spots which are energetically preferred by the polymer chain. The day will cover various aspects, both from the physics and the probabilistic perspective.

List of speakers: K. Alexander (Los Angeles), F. Comets (Paris), G. Giacomin (Paris), C. Monthus (Saclay), S. Whittington (Toronto), K.J. Wiese (Paris).
