摘要
Exchange of stability between periodic orbits of the same winding number is observed in a one-parameter family of quartic potentials. We use numerical simulations to study the exchanges that occur between two values of the parameter for which the system is integrable. The relevance for the survival of Kolmogorov-Arnold-Moser tori is briefly discussed and parallels are drawn to a similar phenomenon earlier observed for area-preserving maps.
