Dynamics on Graphs

By Rick Durrett, Duke U.

An extensive rewrite of the 2007 book Random Graph Dynamics. The new version studies a wide varitey of dynamics on a small number of graphs, primarily the configuration model and inhomogeneous random graphs, which of course contain Erdos-Renyi and random regular graphs as special cases. *'s indicate sections that are not yet written.
