A period doubling, quadrupling, etc., that accompanies the onset of Chaos. It represents the sudden appearance of a qualitatively different solution for a nonlinear system as some parameter is varied. Bifurcations come in four basic varieties: Flip Bifurcation, Fold Bifurcation, Pitchfork Bifurcation, and Transcritical Bifurcation (Rasband 1990).
