-theoretic model of attack and defense of a network in which the defender's objective is to maintain network connectivity and the … attacker's objective is to destroy a set of nodes that disconnects the network. The conflict at each node is modeled as a … which a single random [minimal] set of nodes that disconnects the network is attacked …

This paper presents a model of local network effects in which agents in a social network each value the adoption of a … graph, and that are complete graphs (a standard model of network effects). The structure of the network of adopting agents …
