Finite-time rotation number: a fast indicator for chaotic dynamical structures
J. D. Szezech, A. B. Schelin, I. L. Caldas +3
Lagrangian coherent structures are effective barriers, sticky regions, that separate phase space regions of different dynamical behavior. The usual way to detect such structures is…
Synchronization time in a hyperbolic dynamical system with long-range interactions
Rodrigo Frehse Pereira, Sandro Ely de Souza Pinto, Sergio Roberto Lopes
We show that the threshold of complete synchronization in a lattice of coupled non-smooth chaotic maps is determined by linear stability along the directions transversal to the syn…
Periodic orbit analysis at the onset of the unstable dimension variability and at the blowout bifurcation
Rodrigo Frehse Pereira, Sandro Ely de Souza Pinto, Ricardo L. Viana +2
Many chaotic dynamical systems of physical interest present a strong form of nonhyperbolicity called unstable dimension variability (UDV), for which the chaotic invariant set conta…
