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

Figure 4

Illustration of the saddle-node bifurcation (part II). The pathway has become monostable. Magnification (not shown) of the top left corner of the phase space reveals that the nullclines do not intersect each other in this area. This is because the asymmetry of the pathway model has increased as compared to Figure 3. Parameters: , , and .
