On considère des problèmes d’optimisation de forme pour des fonctionnelles intégrales générales, parmi les domaines Ω parcourant tous les sous-domaines d’un domaine borné D donné de ℝ d . Nous montrons de manière assez élémentaire l’existence d’une solution qui en général est un ensemble quasi ouvert. Sous des conditions très faibles, nous prouvons que le domaine optimal est en fait ouvert et de périmètre fini. Des contre-exemples montrent que ce n’est pas toujours le cas.

We consider shape optimization problems for general integral functionals of the calculus of variations, defined on a domain Ω that varies over all subdomains of a given bounded domain D of ℝ d . We show in a rather elementary way the existence of a solution that is in general a quasi open set. Under very mild conditions we show that the optimal domain is actually open and with finite perimeter. Some counterexamples show that in general this does not occur.
