Survival and extinction of epidemics on random graphs with general degrees
arXiv: Probability, 2019.
In this paper, we establish the necessary and sufficient criterion for the contact process on Galton-Watson trees (resp. random graphs) to exhibit the phase of extinction (resp. short survival). We prove that the survival threshold $lambda_1$ for a Galton-Watson tree is strictly positive if and only if its offspring distribution $xi$ has ...More
