A characteristic property of networks is their ability to propagate
influences, such as infectious diseases, behavioral changes, and failures. An
especially important class of such contagious dynamics is that of cascading
processes. These processes include, for example, cascading failures in
infrastructure systems, extinctions cascades in ecological networks, and
information cascades in social systems. In this review, we discuss recent
progress and challenges associated with the modeling, prediction, detection,
and control of cascades in networks.
