Symmetry-breaking phase transition in a dynamical decision model
Gaultier Lambert, Guillaume Chevereau, Eric Bertin
We consider a simple decision model in which a set of agents randomly choose one of two competing shops selling the same perishable products (typically food). The satisfaction of a…
Commuter networks and community detection: a method for planning sub regional areas
Andrea De Montis, Simone Caschili, Alessandro Chessa
A major issue for policy makers and planners is the definition of the "ideal" regional partition, i.e. the delimitation of sub-regional domains showing a sufficient level of homoge…
Irrelevance of information outflow in opinion dynamics models
Claudio Castellano, Romualdo Pastor-Satorras
The Sznajd model for opinion dynamics has attracted a large interest as a simple realization of the psychological principle of social validation. As its most salient feature, it ha…
Socio-economic utility and chemical potential
Rémi Lemoy, Eric Bertin, Pablo Jensen
In statistical physics, the conservation of particle number results in the equalization of the chemical potential throughout a system at equilibrium. In contrast, the homogeneity o…
Collaborate, compete and share
Emanuele Pugliese, Claudio Castellano, Matteo Marsili +1
We introduce and study a model of an interacting population of agents who collaborate in groups which compete for limited resources. Groups are formed by random matching agents and…
Critical transient in the Barabási model of human dynamics
Andrea Gabrielli, Guido Caldarelli
We introduce an exact probabilistic description for L=2 of the Barabási model for the dynamics of a list of L tasks. This permits to study the problem out of stationarity, and to s…
