A Canonical Model of Multistability and Scale-Invariance in Biological Systems
Figure 2
Varying β for a fixed λ = 4 yields a subcritical Hopf bifurcation.
A: Bifurcation diagram for state parameter β showing the region of bistability. Attracting solutions shown in solid. The unstable repellor (or seperatrix) is shown as the dotted curve. The fixed point loses stability at β = 0. B: The geometry of equation (1) for three different values of β. Attractors are shown as solid diamonds and repellors as open diamonds. Bistability corresponds to the blue setting.
