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…
Emergence of clustering, correlations, and communities in a social network model
Marian Boguna, Romualdo Pastor-Satorras, Albert Diaz-Guilera +1
We propose a simple model of social network formation that parameterizes the tendency to establish acquaintances by the relative distance in a representative social space. By means…
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…
Search and Congestion in Complex Networks
Alex Arenas, Antonio Cabrales, Albert Diaz-Guilera +2
A model of communication that is able to cope simultaneously with the problems of search and congestion is presented. We investigate the communication dynamics in model networks an…
