Every spring semester

The course provides an introduction to and some analysis of the main mathematical models used to describe large networks and dynamical processes that evolve on networks. Motivation and applications will be drawn from social, economic, natural, and infrastructure networks, as well as networked decision systems such as sensor networks.

Basic graph theory: connectivity, degree distributions, trees, adjacency matrices, spectrum.
Random graphs: Erdos-Renyi, configuration model, preferential attachment, small-world, branching process approximations
Flows and games on graphs: max-flow, min-cut, optimal transport, Wardrop equilibria, evolutionary dynamics.
Random walks on graphs: invariant distributions, hitting times, mixing times.
Dynamical systems on graphs: distributed averaging, interacting particle systems, epidemics, opinion dynamics. Mean-field and branching process approximations.
