  skos:definition """La théorie des systèmes dynamiques désigne couramment la branche des mathématiques qui s'efforce d'étudier les propriétés d'un système dynamique. Cette recherche active se développe à la frontière de la topologie, de l'analyse, de la géométrie, de la théorie de la mesure et des probabilités. La nature de cette étude est conditionnée par le système dynamique étudié et elle dépend des outils utilisés (analytiques, géométriques ou probabilistes).

When differential equations are employed, the theory is called continuous dynamical systems. From a physical point of view, continuous dynamical systems is a generalization of classical mechanics, a generalization where the equations of motion are postulated directly and are not constrained to be Euler–Lagrange equations of a least action principle. When difference equations are employed, the theory is called discrete dynamical systems. When the time variable runs over a set that is discrete over some intervals and continuous over other intervals or is any arbitrary time-set such as a Cantor set, one gets dynamic equations on time scales. Some situations may also be modeled by mixed operators, such as differential-difference equations.
