THREE-FREQUENCY RESONANCES IN DYNAMICAL SYSTEMS (original) (raw)

Int. J. Bifurcation and Chaos, 9, 2181-2187 We investigate numerically and experimentally dynamical systems having three interacting frequencies: a discrete mapping (a circle map), an exactly solvable model (a system of coupled ordinary differential equations), and an experimental device (an electronic oscillator). We compare the hierarchies of three-frequency resonances we find in each of these systems. All three show similar qualitative behaviour, suggesting the existence of generic features in the parameter-space organization of three-frequency resonances. *
