Figure 3: Numerical simulations of system (5), a = 10/3, b = 10, and the initial values (0.1, 0.1, 0.2). (a) Bifurcation diagram of the local maxima of the variable z about the order α; (b) first two Lyapunov exponents of Case 1; (c) bifurcation diagram of the local maxima of the variable z about the parameter L; (d) first two Lyapunov exponents of Case 2.
