Abstract
A stimulating development in the analysis of complex systems has been the hypothesis of self organized criticality 1,2. The main assumption is that such systems evolve towards a state where small perturbations can give rise to changes (catastrophes) of all sizes. This state describes the most unstable situation compatible with some kind of equilibrium. The distribution of catastrophes, because of its inherent scale invariance, is characterized by power laws. In previous work, we have checked that this hypothesis is well satisfied in systems which evolve into a steady state far from equilibrium3. The model we analyzed is Diffusion Limited Aggregation4, for which a comprehensive amount of work is already available4.
