Epidemic spreading on uncorrelated heterogenous networks with non-uniform transmission

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. Wi...

Description
Summary: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 λ 0 from the transmission, we analyzed the effects of degree distribution P ( k ) and transmission distribution λ ( k ) on the threshold of λ 0 .
