Résumé : Équations aux dérivées partielles et applications. Actes de l'école du CIMPA, Lanzhou, 2004 Ce volume comprend des versions élargies des notes de cours de l'école du CIMPA à Lanzhou, juillet 2004. Ces textes donnent un survol, y compris les progrès les plus récents, sur certains thèmes en analyse des équations aux dérivées partielles d'origine physique, mécanique ou géométrique tels que : l'équation de Korteweg-de Vries, les applications harmoniques, la forme normale de Birkhoff and le théorème de KAM pour des systèmes dynamiques de dimension infinie, le tourbillon de l'équation d'Euler, l'analyse semi-classique des équations de Schrödinger et de Dirac, et des situations limites des équations elliptiques semi-linéaires. La plupart des textes pourraient être lus par des étudiants ou des chercheurs débutants qui s'intéressent à ces sujets. Mots clefs : Systèmes complètement intégrables, équations de Korteweg-de Vries, applications harmoniques, forme normale de Birkhoff, théorie KAM, EDP Hamiltoniènnes, dynamique des fluides, tourbillon, confinement, fluide incompressible, limite semi-classique, états cohérents, équation de Schrödinger, équation de Dirac, estimation de Gevrey, principe d'absorption limite, estimations microlocales de la résolvante, mesures semi-classiques, Hamiltonien de Floquet, EDP elliptique semi-linéaire Abstract: This volume contains expanded versions of lecture notes of CIMPA's school held in Lanzhou, July 2004. These texts offer a detailed survey, including the most recent advances, of some topics in analysis of partial differential equations arising from physics, mechanics and geometry such as: Korteweg-de Vries equation, harmonic maps, Birkhoff normal form and KAM theorem for infinite dimensional dynamical systems, vorticity of Euler equation, semi-classical analysis of Schrödinger and Dirac equations, and limiting situations of semilinear elliptic equations. They are mainly aimed at students and young researchers interested in these subjects.
