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

Figure 9

Eigenvalues (a) and (b) computed from (3), (4), and (22) for the state (low), (high) (solid lines) and the state (high), (low) (dashed line) shown in Figure 5 as functions of . Magnifying (not shown) the top parts of the two panels reveals that converges to zero when approaching the saddle-node bifurcation points, whereas assumes a finite negative value. Parameters: ; all other parameters are as in Figure 5.
