In this paper, we reconsider the analytical results on the existence of cyclical fluctuations in continuous time dynamic optimization models with two state variables and their applications to dynamic economic theory. In the first part of the paper, we survey the useful analytical results which were obtained by Dockner and Feichtinger(1991), Liu(1994) and Asada and Yoshida(2003) on the general t...

Résumé. L’utilisation de modèles de procédure chirurgicale (Surgical Process Model, SPM) a récemment émergé dans le domaine de la conception d’outils d’intervention chirurgicale assistée par ordinateur. Ces modèles, qui sont utilisés pour analyser et évaluer les interventions, représentent des procédures chirurgicales (Surgical Process, SP) qui sont formalisées comme des structures symboliques ...
