Non-equilibrium phase transition in negotiation dynamics
A. Baronchelli, L. Dall'Asta, A. Barrat +1
We introduce a model of negotiation dynamics whose aim is that of mimicking the mechanisms leading to opinion and convention formation in a population of individuals. The negotiati…
A Yule-Simon process with memory
C. Cattuto, V. Loreto, V. D. P. Servedio
The Yule-Simon model has been used as a tool to describe the growth of diverse systems, acquiring a paradigmatic character in many fields of research. Here we study a modified Yule…
Non-equilibrium dynamics of language games on complex networks
Luca Dall'Asta, Andrea Baronchelli, Alain Barrat +1
The Naming Game is a model of non-equilibrium dynamics for the self-organized emergence of a linguistic convention or a communication system in a population of agents with pairwise…
Phase ordering and symmetries of the Potts model
Miguel Ibanez de Berganza, Vittorio Loreto, Alberto Petri
We have studied the ordering of the q-colours Potts model in two dimensions on a square lattice. On the basis of our observations we propose that if q is large enough the system is…
Collaborative Tagging and Semiotic Dynamics
Ciro Cattuto, Vittorio Loreto, Luciano Pietronero
Collaborative tagging has been quickly gaining ground because of its ability to recruit the activity of web users into effectively organizing and sharing vast amounts of informatio…
Measuring complexity with zippers
Andrea Baronchelli, Emanuele Caglioti, Vittorio Loreto
Physics concepts have often been borrowed and independently developed by other fields of science. In this perspective a significant example is that of entropy in Information Theory…
