Interdependent Graphs
Interdependent graphs or networks is a system of coupled networks where nodes of one or more networks depend on nodes in other networks. This dependency is enhanced by the developments in modern technology. Such dependencies may lead to cascading failures between the networks and a relatively small damage can lead to a catastrophic breakdown of the system. Blackouts are a fascinating demonstration of the important role played by the dependencies between networks. A recent study developed a framework to study the cascading failures in an interdependent networks system
