Witryna1 sty 2024 · The imperfect pitchfork-like bifurcation has a non-bifurcating branch and an additional imperfect bifurcation. The bifurcation regions and features are explored … WitrynaThis bifurcation is called a saddle-node bifurcation. In it, a pair of hyperbolic equilibria, one stable and one unstable, coalesce at the bifurcation point, annihilate each other and disappear.1 We refer to this bifurcation as a subcritical saddle-node bifurcation, since the equilibria exist for values of below the bifurcation value 0.

Witryna30 maj 2024 · A bifurcation occurs in a nonlinear differential equation when a small change in a parameter results in a qualitative change in the long-time solution. Examples of bifurcations are when fixed points are created or destroyed, or change their stability. (a) (b) Figure 11.2: Saddlenode bifurcation. (a) ˙x versus x; (b) bifurcation diagram.

WitrynaIn addition, this equation is a typical amplitude equation for imperfect steady bifurcations with cubic nonlinearities. Whenδ=0, we have found thatλ=0 is not the point where the bifurcation transition is observed. This transition appears at a valueλ =λ j > 0. We call λj the delay of the bifurcation transition.
