Riddling in Chaotic Systems

Riddling and related bifurcations in dynamical systems with symmetric invariant subspaces have been an area of recent study. Riddling refers to the situation where the basin of a chaotic attractor is riddled with holes that belong to the basin of another attractor. Current directions of research consist of theoretical, numerical, and experimental exploration of various physical consequences associated with riddling and related bifurcations. One such consequence is on-off intermittency. The presentations in this minisymposium deal with several forefront problems on riddling. Topics to be covered include riddling bifurcation, blowout bifurcation, intermingled basins, and on-off intermittency in coupled map lattices, and unstable periodic-orbit theory of blowout bifurcation.
