Synchronization and structure in an adaptive oscillator network
Pablo M. Gleiser, Damián H. Zanette
We analyze the interplay of synchronization and structure evolution in an evolving network of phase oscillators. An initially random network is adaptively rewired according to the…
Two dimensional Ising model with long-range competing interactions
Sergio A. Cannas, Pablo M. Gleiser, Francisco A. Tamarit
The two-dimensional Ising model with competing short range ferromagnetic interactions and long range antiferromagnetic interactions is perhaps the most simple one containing the mi…
Community analysis in social networks
Alex Arenas, Leon Danon, Albert Diaz-Guilera +2
We present an empirical study of different social networks obtained from digital repositories. Our analysis reveals the community structure and provides a useful visualising techni…
Nonequilibrium phase transition in a model for the propagation of innovations among economic agents
M. Llas, P. M. Gleiser, J. M. Lopez +1
We characterize the different morphological phases that occur in a simple one-dimensional model of propagation of innovations among economic agents [X.\ Guardiola, {\it et. al.}, P…
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…
