Abstract

We investigate the susceptible-infected-susceptible dynamics on configuration model networks. In an effort for the unification of current approaches, we consider a network whose edges are constantly being rearranged, with a tunable rewiring rate ω\omega. We perform a detailed stationary state analysis of the process, leading to a closed form expression of the absorbing-state threshold for an arbitrary rewiring rate. In both extreme regimes (annealed and quasi-static), we recover and further improve the results of current approaches, as well as providing a natural interpolation for the intermediate regimes. For any finite ω\omega, our analysis predicts a vanishing threshold when the maximal degree kmaxk_\mathrm{max} \to \infty, a generalization of the result obtained with quenched mean-field theory for static networks.
