Evolution of Social Power in Social Networks with Dynamic Topology

Ye, Ben; Liu, Ji; Anderson, Brian; Yu, Changbin (Brad); Basar, Tamer


The recently proposed DeGroot-Friedkin model describes the dynamical evolution of individual social power in a social network that holds opinion discussions on a sequence of different issues. This paper revisits that model, and uses nonlinear contraction analysis, among other tools, to establish several novel results. First, we show that for a social network with constant topology, each individual's social power converges to its equilibrium value exponentially fast, whereas previous results...[Show more]
