"This volume contains papers that expose the state of the art in mathematical techniques for analyzing such systems. Recently developed geometric ideas are highlighted in work that includes a theory of relaxation-oscillation phenomena in higher dimensional phase spaces. Subtle exponentially small effects result from singular perturbations implicit in certain multiple-time-scale systems. Their role in the slow motion of fronts, bifurcations, and jumping between invariant tori is all explored here.

Neurobiology has played a particularly stimulating role in the development of these techniques, and one paper is directed specifically at applying geometric singular perturbation theory to reveal the synchrony in networks of neural oscillators."--BOOK JACKET.
