Effects of regulation on a self-organized market
G. Cuniberti, A. Valleriani, J. L. Vega
Adapting a simple biological model, we study the effects of control on the market. Companies are depicted as sites on a lattice and labelled by a fitness parameter (some `company-s…
Semiclassical Theory of Integrable and Rough Andreev Billiards
W. Ihra, M. Leadbeater, J. L. Vega +1
We study the effect on the density of states in mesoscopic ballistic billiards to which a superconducting lead is attached. The expression for the density of states is derived in t…
Damage-Spreading in Self-Organized Critical Systems
Raffaele Cafiero, Angelo Valleriani, Josè Luis Vega
We study the behavior under perturbations of different versions of Bak-Sneppen (BS) model in 1 + 1 dimension. We focus our attention on the damage-spreading features of the BS mode…
Extremal Coupled Map Lattices
Guillermo Abramson, Jose Luis Vega
We propose a model for co-evolving ecosystems that takes into account two levels of description of an organism, for instance genotype and phenotype. Performance at the macroscopic…
