Par <I>sc&#233;nario</I>, il faut essentiellement comprendre une conjecture sur le comportement d'un syst&#232;me donnant une ``explication'' simplifi&#233;e et plausible de la cascade de bifurcation qu'il subit lorsque les param&#232;tres de contr&#244;le varient. Cette conjecture repose sur l'hypoth&#232;se d'un syst&#232;me bifurquant. La diff&#233;rentiation des sc&#233;narios d&#233;coulera d'une hypoth&#232;se suppl&#233;mentaire de r&#233;sonance ou de non-r&#233;sonnance, de super-criticalit&#233; ou de sous-criticalit&#233;.
