Epidemic spreading on uncorrelated heterogenous networks with non-uniform transmission

摘要

We investigate the combinational effects of non-uniform transmission of edges and the network structure in susceptible-infected-removed models of the epidemic spreading. Here the degree-degree correlation is neglected and the transmission of individual edge depends on the degree of infected node. With the additional assumption that we can compartment a independent factor 0 from the transmission, we analyzed the effects of degree distribution P(k) and transmission distribution lambda(k) on the threshold of lambda(0).
