Stochastic Modelling of Interacting Systems

Abstract

The present project is the continuation of the previous projetos temáticos: dynamical phase transitions in evolutionary systems, large deviations, diffusion and localization, (1991 to 1994) and critical phenomena in evolutionary processes and equilibrium systems(in two editions, 1995 to 1998, and from 2000 to 2004). They all were highly sucessful and triggered a remarkable increase in the level of activity, prestige and recognition of theparticle-systems group at USP and UNICAMP. The research activities for the next four-year period will focus on central topics of the theory of probability, statistical mechanics and related areas. In particular: Properties of various stochastic processes and fields, percolation, interacting particle systems, hydrodinamical limits, rate of convergence to equilibrium, random surfaces, growth processes, random networks, stochastic flows, processes in random environment, disordered systems, inference of stochastic processes, stochastic models in finance, scaling limit and aging of dynamics of disordered systems, stochastic clusters, gene expression systems, statistical genomics.
