Advertising and irreversible opinion spreading in complex social networks
Irreversible opinion spreading phenomena are studied on smallworld and scale-free networks by means of the magnetic Eden model, a nonequilibrium kinetic model for the growth of binary mixtures in contact with a thermal bath. In this model, the opinion of an individual is affected by those of their acquaintances, but opinion changes (analogous to spin flips in an Ising-like model) are not allowe...
متن کاملDisease spreading in scale-free networks
We study the spreading of a disease on a population whose connectivity obeys a scaling law, a characteristic of real-life networks, by using the standard SIR model. We show that for scale-free networks with a high degree of connectivity there is no critical threshold for epidemics, but the infected population grows almost linearly with the infection probability, which is more realistic, as oppo...
متن کاملEpidemic spreading in scale-free networks.
The Internet has a very complex connectivity recently modeled by the class of scale-free networks. This feature, which appears to be very efficient for a communications network, favors at the same time the spreading of computer viruses. We analyze real data from computer virus infections and find the average lifetime and persistence of viral strains on the Internet. We define a dynamical model ...
متن کاملDisease Spreading in Structured Scale-Free Networks
We study the spreading of a disease on top of structured scale-free networks recently introduced. By means of numerical simulations we analyze the SIS and the SIR models. Our results show that when the connectivity fluctuations of the network are unbounded whether the epidemic threshold exists strongly depends on the initial density of infected individuals and the type of epidemiological model ...

The Internet, as well as many other networks, has a very complex connectivity recently modeled by the class of scale-free networks. This feature, which appears to be very efficient for a communications network, favors at the same time the spreading of computer viruses. We analyze real data from computer virus infections and find the average lifetime and prevalence of viral strains on the Intern...
