Lu, Dan (author), Yang, Shunkun (author), Zhang, Jiaquan (author), Wang, H. (author), Li, Daqing (author)Epidemic propagation on complex networks has been widely investigated, mostly with invariant parameters. However, the process of epidemic propagation is not always constant. Epidemics can be affected by various perturbations and may bounce back to its original state, which is considered resilient. Here, we study the resilience of epidemics on...journal article 2017
