Complex Networks: Dynamics of Networks - January 10-12, 2011

The changing structure of networks over time impact and are indeed inherent in the study of a broad array of network phenomena. The network of contacts for the spread of an infectious disease varies in time, with that variation playing a potentially important role in the course of the disease. Ad hoc communications networks between roaming elements must continously readjust and renavigate between nodes according to the changing landscape of connections. Political networks of association connections or voting similarities vary from one legislative session to the next.

The detailed local social and/or technological processes underlying each of these example applications obviously differ, but many of the basic mathematical and statistical questions regarding such networks and the generalized information they carry are similar.  Though the importance of dynamics in networks has of course been long recognized, renewed interest has emerged in part due to the increasing accessibility of dynamic network data, ranging from longitudinal data waves to complete time histories of network evolution.  Additionally, most of the theoretical modeling work that has been done on the dynamics of networks has been focused on the statistical equilibria of those models (e.g., growing networks by preferential attachment) or on one-time disruption events (e.g., the effect of knocking out hubs).  At the same time, statistical and computational tools for analyzing time-varying networks remain relatively few in number, especially as compared to the wealth of advances in methods for modeling and analyzing static networks.

There thus remains an ongoing need and opportunity for more thorough mathematical and statistical analysis and modeling of dynamic networks. This workshop aims to bring together researchers interested in pushing forward this extremely fertile area of research.

Organizers: Eric Kolaczyk (Boston University), Peter Mucha (UNC-Chapel Hill), Mason Porter (Oxford University), Stephen Fienberg (Carnegie Mellon University), Jim Moody (Duke University), Raissa D'Souza (University of California - Davis).

This workshop will be held at SAMSI.



Please make reservations at the Radisson RTP as soon as possible. The SAMSI room block and rate ($109) is effective until December 23, 2010. After this date, there is no guarantee a room will be available.  If you have a change in plans, individual room reservations must be cancelled 72 hours prior to arrival. Check-in is at 3:00 PM; check-out is 12:00 noon.
