摘要: We numerically investigate the existence of a threshold for epidemic outbreaks in class scale-free networks characterized by parametrical dependence scaling exponent, influencing the convergence fluctuations degree distribution. In finite-size networks, finite thresholds for spreading an epidemic are always found. However, both and the behavior epidemic prevalence quite different with respect to type network considered system size. We also discuss agreements differences with some analytical claims previously reported.
