Bifurcation

A bifurcation occurs when a smooth variation of the parameters of a Dynamical system results in a sudden qualitative change in behaviour.

Local bifurcations

Local bifurcations occur at non-hyperbolic fixed points and change the number of fixed points.¹ The codimension refers to the number of parameters.
