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

Figure 5

Bifurcation diagram of the bistable pathway model (9) acting as a switch for a particular value of when varying the degree of asymmetry. The stationary solutions are plotted versus the control parameter values . The solutions were computed from (18), (19), (20), and (21). Solid line: asymptotically stable fixed points of the state (low), (high). Dotted line: unstable fixed points in the bistable parameter domain. Dashed line: asymptotically stable fixed points of the state (high), (low). Parameters: , , and .
