Stability and Hopf Bifurcation Analysis in a Delayed Myc/E2F/miR-17-92 Network Involving Interlinked Positive and Negative Feedback Loops

Figure 2

(a) Bifurcation diagram of [P] with as a bifurcation parameter. The red solid lines depict stable steady states and the black dashed line depicts unstable steady states. The maxima and minima are depicted by the blue dots and green dots for the stable and unstable limit cycle, respectively. The bifurcation points of the subcritical Hopf bifurcation are marked as sub and LPC as fold limit cycle bifurcation points. (b), (c), and (d) are time courses diagram of and for the parameter =0.01(b), 0.05(c), and 0.09 (d), respectively. The initial conditions: .
