Cr. Deoliveira et Ps. Goncalves, BIFURCATIONS AND CHAOS FOR THE QUASI-PERIODIC BOUNCING BALL, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 56(4), 1997, pp. 4868-4871
We investigate the influence of a second frequency on the classical pe
riodic bouncing-ball problem, and call it the quasiperiodic bouncing b
all. We indicate how to compute the Lyapunov exponent for implicit map
s and confirm the presence of chaos for the periodic bouncing ball. We
have numerically found a series of nontrivial bifurcations for the qu
asiperiodic bouncing ball. We have also found several cases of nonperi
odic attractors with negative Lyapunov exponents.
