Phase plot of the (I, S) plane.
A – Case g=2, the trajectories starting at (4.6316, 1.9) and (6.16(6), 1.2) are indicated with dots. This corresponds to the phase plot given in [10, Fig. 1A] for α = 0.1, β = 0.2. B – Case g=12, the trajectories, starting at (13.81(81), 1.1) and (15.3(3), 0.6) are indicated with dots. This corresponds to the phase plot given in [10, Fig. 1B] for α = 0.1, β = 1.2.
