Age-targeted failure in evolving networks with addition and deletion of vertices

RESUMO

We present a message passing formalism to study the age-targeted robustness of networks that have evolved under the addition and deletion of vertices. We show that in the growing regime removing the oldest vertices fragments the network far sooner than random failure, while the oldest core is far more robust under targeted removal of the young. At a balanced turnover of vertices the attack value vanishes identically and we prove that the giant component is invariant under arbitrary age-targeting.
