We present extensive numerical simulations of the Axelrod's model for social influence, aimed at understanding the formation of cultural domains. This is a nonequilibrium model with short rangeâ€¦ (More)

We study analytically a simple game theoretical model of heterogeneous interacting agents. We show that the stationary state of the system is described by the ground state of a disordered spin modelâ€¦ (More)

By considering diffusion on De Bruijn graphs, we study in detail the dynamics of the histories in the minority game, a model of competition between adaptative agents. Such graphs describe theâ€¦ (More)

We introduce a simple continuous model for nonequilibrium surface growth. The dynamics of the system is defined by the Kardar-Parisi-Zhang equation with a Morse-like potential representing a shortâ€¦ (More)

A modified Kardar-Parisi-Zhang (KPZ) equation is introduced, and solved exactly in the infinite-range limit. In the low-noise limit the system exhibits a weak-to-strong coupling transition, roundedâ€¦ (More)
