Network dynamics
This article explores dynamic networks and diffusion, with particular emphasis on evolving traces of enacted social relations. It begins with a review of models for the evolution of networks over time - making a distinction between ‘node-based’ and ‘edge-based’ models - and more specifically how and why networks change. It then considers how network timing affects the flow of things across networks, focusing on how edge timing reshapes the set of paths potentially useful for diffusion. It also discusses the structure requirements for network diffusion and shows how these requirements are affected when we assume edges come and go over time. Finally, it describes the effect of tie order on diffusion potential as well as the correlation between network evolution and diffusion.
