Perturbed Euler top and bifurcation of limit cycles on invariant Casimir surfaces
arXiv:1910.07264 · doi:10.1016/j.physd.2010.04.013
Abstract
Analytical perturbations of the Euler top are considered. The perturbations are based on the Poisson structure for such a dynamical system, in such a way that the Casimir invariants of the system remain invariant for the perturbed flow. By means of the Poincaré-Pontryagin theory, the existence of limit cycles on the invariant Casimir surfaces for the perturbed system is investigated up to first order of perturbation, providing sharp bounds for their number. Examples are given.
