a(γ = 2.5), b(γ = 4)
Figure 12.11 depicts the region D(1,1) in the plane ( p, R) with a set of parameters
ε = 0.02, γ = 2.5, φ = 0.52, μ = 0.1, k = 0, ,k = 0, and different values
γ = 2.5(Fig. 12.11a) γ = 4(Fig. 12.11b).
Figures 12.13 and 12.14 present bifurcation diagrams for R = 0.25, plotted with
the same set of parameters as in Fig. 12.11.
Figure 12.12 shows that the main mode with m 1 = 1, m 2 = 1 exists at 0.116 ≤
p ≤ 0.125; at 0.112 ≤ p ≤ 0.116m 1 = 2, m 2 = 2, p = 0.116 is bifurcation
