This 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.

This 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. With the opposite sign x t = x2, the equilibria appear at File Size: KB. A saddle-node bifurcation is a local bifurcation in which two (or more) critical points (or equilibria) of a differential equation (or a dynamic system) collide and annihilate each other. Saddle-node bifurcations may be associated with hysteresis and catastrophes. Consider the slope function $$f(x, \alpha),$$ where α is a control parameter. In this example, we use α instead of k because. subcritical saddle-node bifurcation, and the remaining two equilibria annihilate each other. 6. 4.

(b) Show that the PDE has traveling wave solutions. There is no fundamental reason why a limit cycle should appear at a saddle-node bifurcation. Indeed, in one-dimensional differential equations, saddle-node bifurcations are possible, but never lead to a limit cycle. Moreover, if a limit cycle exists in a two-dimensional system, there is no reason why it should appear directly at the bifurcation point - it can also exist before the bifurcation. Bifurcation theory is full of con icting ter-minology! The Saddle-node bifurcation is sometimescalledthe\fold"bifurcation,\turn-ing point" bifurcation or \blue-sky" bifurca-tion (e.g. see Thompson & Stewart ).
