barriers, called robust tori that block the trajectories in certain regions of the phase space. We used the Double-Gyre Flow … system as the model. In this system, the robust tori play the role of a skeleton for the dynamics and block, horizontally …

A Hamiltonian system perturbed by two waves with particular wave numbers can present robust tori, which are barriers … created by the vanishing of the perturbed Hamiltonian at some defined positions. When robust tori exist, any trajectory in … indicate that the considered particular solution for the two waves Hamiltonian model shows plenty of robust tori blocking …

of two permanent robust tori. The process is initialized and concluded through bifurcations of fixed points located on … the robust tori. Our approach is based on a Hamiltonian system derived from the resonant normal form. Choosing a …
