Characterization of Spatiotemporal Chaos
10:00 AM-12:30 PM
Room: Magpie A/B
Despite the identification of spatiotemporal chaos (STC) in many
physical systems, e.g. lasers, fibrillating hearts, convecting
fluids, and flame fronts, a theoretical understanding of STC remains
elusive. Characterization of the STC state is an essential first step
towards the development of a theory. The speakers in this
minisymposium will focus on four directions for characterizing STC,
including the development of order parameters that distinguish
chaotic states, reduced wavelet descriptions of spatiotemporal
chaotic partial differential equations, unstable periodic orbit
analysis of high-dimensional attractors, and the control and
perturbation of spatially extended systems.
