Multiple transitions of the susceptible-infected-susceptible epidemic model on complex networks.
The epidemic threshold of the susceptible-infected-susceptible (SIS) dynamics on random networks having a power law degree distribution with exponent γ>3 has been investigated using different mean-field approaches, which predict different outcomes. We performed extensive simulations in the quasistationary state for a comparison with these mean-field theories. We observed concomitant multiple tr...
متن کاملCorrigendum: Six Susceptible-Infected-Susceptible Models on Scale-free Networks
Spreading phenomena are ubiquitous in nature and society. For example, disease and information spread over underlying social and information networks. It is well known that there is no threshold for spreading models on scale-free networks; this suggests that spread can occur on such networks, regardless of how low the contact rate may be. In this paper, I consider six models with different cont...
متن کاملGriffiths effects of the susceptible-infected-susceptible epidemic model on random power-law networks.
We provide numerical evidence for slow dynamics of the susceptible-infected-susceptible model evolving on finite-size random networks with power-law degree distributions. Extensive simulations were done by averaging the activity density over many realizations of networks. We investigated the effects of outliers in both highly fluctuating (natural cutoff) and nonfluctuating (hard cutoff) most co...
متن کاملNature of the epidemic threshold for the susceptible-infected-susceptible dynamics in networks.
We develop an analytical approach to the susceptible-infected-susceptible epidemic model that allows us to unravel the true origin of the absence of an epidemic threshold in heterogeneous networks. We find that a delicate balance between the number of high degree nodes in the network and the topological distance between them dictates the existence or absence of such a threshold. In particular, ...
متن کاملEpidemic extinction in a generalized susceptible-infected-susceptible model
Abstract We study the extinction of epidemics in a generalized contact process, where a susceptible individual becomes infected with the rate λ when contacting m infective individual(s) simultaneously, and an infected individual spontaneously recovers with the rate μ. By employing WKB approximation for the master equation, the problem is reduced to finding the zero-energy trajectories in an eff...
