Beyond Generalized Synchrony

4:00 PM-6:00 PM
Hibiscus & Ilima (Salon 3 & 4)

Recent work has addressed states of chaos synchronization that are more general than "generalized synchrony." These arise naturally in systems without built-in symmetries or invariant manifolds, as when non-identical chaotic elements are coupled together. The speakers will: (1) review how invariant manifolds lose stability and propose new, more general synchronization criteria; (2) discuss synchronization structures of systems with invertible and non-invertible elements and their implications for synchrony detection; (3) discuss the 'decoherence transition', an experimentally measurable transition applicable to coupled systems of non-identical elements; and (4) discuss global transitions between intermittent and perfect lag synchronization states in non-identical coupled oscillators.
