Optimization as a result of the interplay between dynamics and structure
Mateu Llas, Pablo M. Gleiser, Albert Diaz-Guilera +1
In this work we study the interplay between the dynamics of a model of diffusion governed by a mechanism of imitation and its underlying structure. The dynamics of the model can be…
Modelling diffusion of innovations in a social network
X. Guardiola, A. Diaz-Guilera, C. J. Perez +2
A new simple model of diffusion of innovations in a social network with upgrading costs is introduced. Agents are characterized by a single real variable, their technological level…
Self-organized criticality in evolutionary systems with local interaction
A. Arenas, A. Diaz-Guilera, C. J. Perez +1
This paper studies a stylized model of local interaction where agents choose from an ever increasing set of vertically ranked actions, e.g. technologies. The driving forces of the…
Synchronization, Diversity, and Topology of Networks of Integrate and Fire Oscillators
X. Guardiola, A. Diaz-Guilera, M. Llas +1
We study synchronization dynamics of a population of pulse-coupled oscillators. In particular, we focus our attention in the interplay between networks topological disorder and its…
Self-organized evolution in socio-economic environments
A. Arenas, A. Diaz-Guilera, C. J. Perez +1
We propose a general scenario to analyze social and economic changes in modern environments. We illustrate the ideas with a model that incorporating the main trends is simple enoug…
Mechanisms of synchronization and pattern formation in a lattice of pulse-coupled oscillators
Albert Diaz-Guilera, Conrad J. Perez, Alex Arenas
We analyze the physical mechanisms leading either to synchronization or to the formation of spatio-temporal patterns in a lattice model of pulse-coupled oscillators. In order to ma…
