Synchronization in dynamical networks: basics, some results and applications
Wednesday, November 8th
HP Auditorium, Soda Hall
Professor, Ecole Polytechnique Fédérale de Lausanne
Synchronization is the most prominent form of collective motion in coupled dynamical systems. It is a very old subject in science, but it has regained from time to time new interest. This happened about 15 years ago, when it was realized that systems with chaotic behavior could synchronize. It is happening again with the current interest in large complex networks. The talk will first explain the two parallel notions of synchronization: phase synchronization and state synchronization. Then the phenomenon of synchronization will be illustrated on a few examples. In networks, the presence of synchronization depends on the individual dynamical systems, the strength of interaction and the structure of the network. We present a few mathematical results that make this more precise. Then, various applications in communications and signal processing are briefly presented. Finally, the possible significance of synchronization in neuroscience and physiology in general are mentioned, leading to less stringent notions of synchronization and to the corresponding indicators.
