Epj Manuscript No. Self Organization of Interacting Polya Urns

Abstract

We introduce a simple model which shows non-trivial self organized critical properties. The model describes a system of interacting units, modelled by Polya urns, subject to perturbations and which occasionally break down. Three equivalent formulations-stochastic, quenched and deterministic-are shown to reproduce the same dynamics. Among the novel features… (More)
