Solvable epidemic model on degree-correlated networks
Satoru Morita
Disease and information spread over social and information networks. Understanding the spread phenomena in networks requires paying attention not only to the degree distribution bu…
Type reproduction number for epidemic models on heterogeneous networks
Satoru Morita
Infection can spread easily on networks with heterogeneous degree distribution. Here, we considered targeted immunization on such networks, wherein a fraction of individuals with t…
Six Susceptible-Infected-Susceptible Models on Scale-free Networks
Satoru Morita
Spreading phenomena are ubiquitous in nature and society. For example, disease, rumor, and information spread over underlying social and information networks. It is well known that…
Analytical solution of stochastic model of risk-spreading with global coupling
Satoru Morita, Jin Yoshimura
We study a stochastic matrix model to understand the mechanics of risk-spreading (or bet-hedging) by dispersion. Such model has been mostly dealt numerically except for well-mixed…
Extended Pair Approximation of Evolutionary Game on Complex Networks
Satoru Morita
We investigate how network structure influences evolutionary games on networks. We extend the pair approximation to study the effects of degree fluctuation and clustering of the ne…
