DEF

Attracteur fractal caractéristique du mouvement chaotique et des systèmes turbulents. Pour le définir, il ne suffit pas de caractériser l'espace de phase, comme c'est le cas pour les attracteurs étranges, il faut en plus quantifier le comportement du système dynamique à son égard.

OBS

Cette séparation entre l'aspect métrique et l'aspect dynamique se retrouve de plus en plus dans les nombreuses définitions du concept de «dimension». Le régime chaotique se distingue par un exposant de Liapounov positif.
