The power spectrum of geodesic divergences as an early detector of chaotic motion
Ch. L. Vozikis, H. Varvoglis, K. Tsiganis
We propose a new method for determining the stochastic or ordered nature of trajectories in non-integrable Hamiltonian dynamical systems. The method consists of constructing a time…

Order and chaos in galactic maps
N. D. Caranicolas, Ch. L. Vozikis
We investigate the properties of motion in a map model derived from a galactic Hamiltonian made up of perturbed elliptic oscillators. The phase space portrait is obtained in all th…

Imperfect fractal repellers and irregular families of periodic orbits in a 3-D model potential
B. Barbanis, H. Varvoglis, Ch. L. Vozikis
A model, plane symmetric, 3-D potential, which preserves some features of galactic problems,is used in order to examine the phase space structure through the study of the propertie…
