Do voters choose rationally, irrationally or at random? Data and theory for proportional elections
Volker Hösel, Johannes Müller, Aurélien Tellier
Data of proportional elections show a striking feature: If the parties are ranked according to the number of their voters, the number of votes grows exponentially with the rank of…
Phase transitions in Pareto optimal complex networks
Luís F Seoane, Ricard Solé
The organization of interactions in complex systems can be described by networks connecting different units. These graphs are useful representations of the local and global complex…
Analytic solution of a model of language competition with bilingualism and interlinguistic similarity
Victoria Otero-Espinar, Luís F. Seoane, Juan J. Nieto +1
An in-depth analytic study of a model of language dynamics is presented: a model which tackles the problem of the coexistence of two languages within a closed community of speakers…
On the Origins of Hierarchy in Complex Networks
Bernat Corominas-Murtra, Joaquín Goñi, Ricard V. Solé +1
Hierarchy seems to pervade complexity in both living and artificial systems. Despite its relevance, no general theory that captures all features of hierarchy and its origins has be…
Exploring the randomness of Directed Acyclic Networks
Joaquín Goñi, Bernat Corominas-Murtra, Ricard V. Solé +1
The feed-forward relationship naturally observed in time-dependent processes and in a diverse number of real systems -such as some food-webs and electronic and neural wiring- can b…
