MS14
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.
