MS54
Bifurcation with Euclidean Symmetry

10:00 AM-12:00 PM
Room: Superior B

There have been many recent developments in dynamical systems with Euclidean symmetry (or spatially extended systems), with a wide range of applications including Rayleigh-Bénard convection and Ginzburg-Landau theory, the formation and transitions of spirals in reactive media, and the control of underwater vehicles. The speakers in this minisymposium will provide a survey of several of these developments and applications.
