The Lyapunov exponents of the system (1) versus parameter h: for the chaotic attractor (black curves) and for the trivial attractor, the fixed point at the origin (gray line). Parameter values are , T = 6, , a = 6.5.
Constructing the amplitude stroboscopic map at , a = 6.5, T = 6, for different values of parameter h: (a) the original diagram accounting all accumulated computational data, and (b) the idealized plot excluding the widening by the phase averaging.
Diagrams illustrating dynamics of phase on successive stages of excitation of the first oscillator on the attractor A (black) and on the non-attracting invariant set S (gray).
(a) Periodic solutions of the equations (1) with period plotted in the extended phase parameter space at , a = 6.5, T = 6, . (b) Superimposed graphs of radial (amplitude) component of the same set of solutions versus parameter h; this is actually a longitudinal slice of (a).
Attractor A and non-attracting invariant set S in the stroboscopic Poincaré section shown on the plane of variables of the first oscillator (a) and in three-dimensional plot (b) accounting a variable of the second oscillator at , a = 6.5, T = 6, , and h = −1.15. The gray color on the panel (a) indicates roughly the basin of attraction of the stable fixed point in the origin.
A plot of radial component of the model map (A1) (a) and disposition of attractors A, O and of a non-attractive invariant set S on the plane of complex variable z (b).
Mutual disposition of attractors A and O and of a non-attractive invariant set (S) of the map (A3) on the plane of complex variable z for different values of parameter R at .
