Fig. 1. Successive maxima of the long-term evolution of x(t)
by Eq. (2) as function of the control parameter A in the
range 0.5 < A < 0.8. Initial
are given by d2x/dt2 = dx/dt
= x = 0.
Fig. 2. Largest Lyapunov exponent (LE) as function of the control
in the same range as in Fig. 1.
Fig. 3. Stereoscopic view of the strange attractor of Eq. (3) for
control parameter value A = 0.6 in order to obtain a
impression. The corresponding Lyapunov exponents are given by (L1,
= (0.035, 0, -0.635)
A GIF animated view of this attractor is available.
