Riassunto

Cet ouvrage aborde l'Optimisation continue � travers les notions de base de l'Analyse Convexe appliqu�e et introduit une approche permettant d'obtenir la convergence de solutions optimales d'une suite de fonctions-objectif vers une solution optimale d'un probl�me donn�; il s'agit de l'�pi-convergence encore appel�e Γ-convergence due � De Georgi. Cette notion est aussi int�ressante � cause du fait qu'en dimension finie, l'�pi-convergence de fonctions propres semi-continues inf�rieurement est �quivalente � la convergence graphique de leurs �pigraphes. L'�pi-convergence peut servir � minimiser certaines fonctions objectif ou d'�nergie �chappant � une �tude classique � cause d'un d�faut de coercivit�, de convexit� ou de r�gularit�. De plus ses applications s'�tendent au Contr�le Optimal (en Recherche Op�rationnelle), � la G�om�trie des Formes et aux Processus Stochastiques.
