Exploiting the Structure of Networks to Determine their Dynamical Behavior
Tues., Oct 20, 2009
2:00 - 3:00 PM
400 Cory (Hughes room)
The behavior of various natural and technological networks is dictated by the structure of interactions rather than by detailed properties of the components. This talk will present analysis and design techniques that exploit the network structure while broadly characterizing the components by their essential properties that are relevant to the ensemble behavior. The first technique to be discussed makes use of input/output properties of the components as abstractions of their detailed models to determine network stability. One such input/output property is passivity which will be shown to be well-suited for several physically relevant network structures. The second technique uses a similar input/output approach to study spatial uniformity rather than stability, and is applicable to synchronization and pattern formation problems. The third technique exploits a clustered structure commonly found in networks for a time-scale-based model reduction. The ideas will be illustrated on mathematical models of biomolecular circuits, Internet congestion control, and cooperative vehicle systems.
