PageRank model of opinion formation on social networks
Kandiah, Vivek; Shepelyansky, Dima L. - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 22, pp. 5779-5793
We propose the PageRank model of opinion formation and investigate its rich properties on real directed networks of the … on a conformist parameter characterizing the opinion formation. We find that the LiveJournal and Twitter networks have a … stronger tendency to a totalitarian opinion formation than the university networks. We also analyze the Sznajd model …

Social networks: Evolving graphs with memory dependent edges
Grindrod, Peter; Parsons, Mark - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 21, pp. 3970-3981
social network data collection and analysis in recent years. Within many such networks the interactions are transient: thus … those networks evolve over time. In this paper we introduce a class of models for such networks using evolving graphs with … memory dependence. In particular we show that such networks may continue evolving forever, or else may quench and become …

Cooperative networks overcoming defectors by social influence
Gomez Portillo, Ignacio - In: Physica A: Statistical Mechanics and its Applications 394 (2014) C, pp. 198-210
We address the cooperation problem in structured populations by considering the prisoner’s dilemma game as a metaphor of the social interactions between individuals with imitation capacity. We present a new strategy update rule called democratic weighted update where the individual’s...

The Medieval inquisition: scale-free networks and the suppression of heresy
Ormerod, Paul; Roach, Andrew P - In: Physica A: Statistical Mechanics and its Applications 339 (2004) 3, pp. 645-652
Qualitative evidence suggests that heresy within the medieval Church had many of the characteristics of a scale-free network. From the perspective of the Church, heresy can be seen as an infectious disease. The disease persisted for long periods of time, breaking out again even when the Church...

Critical brain networks
R. Chialvo, Dante - In: Physica A: Statistical Mechanics and its Applications 340 (2004) 4, pp. 756-765
Highly correlated brain dynamics produces synchronized states with no behavioral value, while weakly correlated dynamics prevents information flow. We discuss the idea put forward by Per Bak that the working brain stays at an intermediate (critical) regime characterized by power-law correlations.
