Unstable Modes and Order Parameters of Bistable Signaling Pathways at Saddle-Node Bifurcations: A Theoretical Study Based on Synergetics

Figure 6

Illustration of the saddle-node bifurcation using the cubic fixed point equation (19). The functions (solid line) and (dashed line) of (19) are plotted versus at the saddle-node bifurcation point in which the states (high) and (low) emerge or disappear. Parameters: ; all other parameters are as in Figure 5.
