Susceptible-infected-susceptible model: a comparison of N-intertwined and heterogeneous mean-field approximations.
We introduce the ε-susceptible-infected-susceptible (SIS) spreading model, which is taken as a benchmark for the comparison between the N-intertwined approximation and the Pastor-Satorras and Vespignani heterogeneous mean-field (HMF) approximation of the SIS model. The N-intertwined approximation, the HMF approximation, and the ε-SIS spreading model are compared for different graph types. We fo...
متن کاملSecond-order mean-field susceptible-infected-susceptible epidemic threshold.
Given the adjacency matrix A of a network, we present a second-order mean-field expansion that improves on the first-order N-intertwined susceptible-infected-susceptible (SIS) epidemic model. Unexpectedly, we found that, in contrast to first-order, second-order mean-field theory is not always possible: the network size N should be large enough. Under the assumption of large N, we show that the ...
متن کاملThe Accuracy of Mean-Field Approximation for Susceptible-Infected-Susceptible Epidemic Spreading with Heterogeneous Infection Rates
The epidemic spreading over a network has been studied for years by applying the mean-field approach in both homogeneous case, where each node may get infected by an infected neighbor with the same rate, and heterogeneous case, where the infection rates between different pairs of nodes are also different. Researchers have discussed whether the mean-field approaches could accurately describe the...
متن کاملAccuracy criterion for the mean-field approximation in susceptible-infected-susceptible epidemics on networks.
Mean-field approximations (MFAs) are frequently used in physics. When a process (such as an epidemic or a synchronization) on a network is approximated by MFA, a major hurdle is the determination of those graphs for which MFA is reasonably accurate. Here, we present an accuracy criterion for Markovian susceptible-infected-susceptible (SIS) epidemics on any network, based on the spectrum of the ...
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...
