Bifurcation theory and catastrophe theory are two highlights in the
study of dynamical systems. Another highlight is celestial mechanics, as
found in EMS-3. The current volume builds on the basic material given in
EMS 1 and can be considered as a continuation of it. The volume is a
survey, intended for readers with some background in dynamical systems,
thus aiming at a higher level than Arnol'd's famous little book,
"Catastrophe Theory".
