On-off Intermittency and Synchronization in Chaotic Systems

1:00 PM-3:00 PM
Anthurium & Ginger (Salon 1 & 2)

This minisymposium will address several problems in two related, active areas of chaos research: on-off intermittency and synchronization. In particular, the speakers will discuss how symmetry-breaking affects on-off intermittency, how low- dimensional chaotic behavior can arise in high-dimensional phase space, how a chaotic flow can be paced in time, and the occurrence of on-off intermittent behavior in the rotations associated with general chaotic flows. These problems arise in high-dimensional chaotic systems such as coupled nonlinear oscillators, which have been an area of intense recent interest. As such, this minisymposium is intended for researchers and graduate students who are interested in high- dimensional systems, coupled differential equations, and coupled map lattices.
