From: On the functional diversity of dynamical behaviour in genetic and metabolic feedback systems
(a) Functions f ( M 2 ) and g ( M 2 ) on the two-dimensional M 1 - M 2 coordinate. Lower (M2l) and upper (M2h) bounds of M2 satisfying the stability condition are indicated on the M2 axes (the figure is produced with parameter values: n1 = 12, n2 = 3, k1 = 1, k2 = 2, k3 = 1, kd1 = 1.2, kd2 = 3, kd3 = 2 and K2 = 0.02). (b) Determining curve f(M3) (solid blue) and g(M3) (dashed purple) on the two-dimensional M1-M3 coordinate.
