Interevent times distribution in Voter-like models — •Juan Fernández-Gracia and Víctor M. Eguíluz — IFISC (UIB-CSIC), Palma de Mallorca, Spain

Motivated by the evidence of non-poissonian distributions in human activity patterns[1] and its impact on interactions on a network[2][3] we study the interevent times distribution on voter-like models of opinion formation. The Voter-model has been used for long time for studying out of equilibrium processes of consensus formation. The distribution of times between consecutive changes of state of a node is investigated for various variations of the voter model on different topologies.
