39Figure 17: Bifurcation diagram <strong>of</strong> Lotka–Volterra family for µ = 0.75Figure 18: Bifurcation diagram <strong>of</strong> Lotka–Volterra family for µ = 1.0<strong>Lyapunov</strong> <strong>exponents</strong> for parameters µ ∈ [0, 1] and ξ ∈ [0, 1] are in Figures 20 and 21.Let us note that for ξ = 0 <strong>the</strong> maximal <strong>Lyapunov</strong> <strong>exponents</strong> <strong>of</strong> S µ,ξ correspond to <strong>the</strong><strong>Lyapunov</strong> <strong>exponents</strong> <strong>of</strong> Logistic family F µ to which <strong>the</strong> restriction <strong>of</strong> S µ,ξ is conjugate.In Figure 22 is plotted <strong>the</strong> sign <strong>of</strong> <strong>the</strong> maximal <strong>Lyapunov</strong> exponent L 1 . Blue colorrepresents negative <strong>Lyapunov</strong> <strong>exponents</strong> and red color represents <strong>the</strong> positive ones. Hereit is easy to see for which choice <strong>of</strong> parameters <strong>the</strong> system is showing chaotic motion, and
