= Bifurcation parameter

A bifurcation parameter labels a family of <dynamical systems> in which a qualitative change of <equilibria> or other invariant sets is studied. Near a simple critical <eigenvalue> crossing, a nonzero derivative with respect to the physical control parameter permits using that eigenvalue itself as a local parameter. At a <codimension-two bifurcation>, two independent parameters are generally needed.
