Coexistence of the Bandcount-Adding and Bandcount-Increment Scenarios

Figure 2

Numerically calculated bifurcation structures in the (𝑏,𝜇)-plane for 𝑎=−0.42 (a), 𝑎=0 (b), 𝑎=0.42 (c), and 𝑏=−2.0⋯−1.0, 𝜇=0⋯3.6. The gray areas in (a) and (c) mark the chaotic domain 𝑄^ch. The dashed lines in (a) and (c) show the locations of the bifurcation scenarios, shown in Figures 1, 3, and 5.

(a) 𝑎<0

(b) 𝑎=0

(c) 𝑎>0
