Cosmological Dynamics of a Hybrid Chameleon Scenario

Figure 6

The phase space trajectories of the model with 𝑚=1.6, 𝑛=0.8, 𝛽=1, and 𝜔=1/3. Like Figure 3, this figure is plotted also for the case with 𝑢=0. With these values of parameters, in contrast to Figure 3, the critical line ℒ₁ is stable attractor, while the critical line ℒ₂ remains unstable. Also, in this case, the critical point M is a repeller.
