Symmetry-breaking Bifurcations: Studies in Control and Exploitation


This talk will highlight some investigations into controlling pattern formation. The approaches exploit the inherent spatial, temporal and spatio-temporal symmetries associated with targeted temporally-periodic patterns. Examples will include delayed-feedback control of symmetrically-coupled nonlinear oscillators, and the design of parametrically-excited surface standing wave patterns. A final study investigates changes, with diminishing resources, of large scale vegetation patterns, and examines the proposal that such transitions can be exploited as early warning signs of desertification.
