  skos:definition """La théorie des bifurcations, en mathématiques et en physique est l'étude de certains aspects des systèmes dynamiques. Une bifurcation intervient lorsqu'un petit changement d'un paramètre physique produit un changement majeur dans l'organisation du système.

Most commonly applied to the mathematical study of dynamical systems, a bifurcation occurs when a small smooth change made to the parameter values (the bifurcation parameters) of a system causes a sudden 'qualitative' or topological change in its behavior. Bifurcations occur in both continuous systems (described by ordinary, delay or partial differential equations) and discrete systems (described by maps).
