Cet article est consacré à la mécanique classique et l’analyse spectrale d’un hamiltonien purement magnétique dans ℝ 2 . On démontre que la dynamique et la théorie spectrale semi-classique peuvent être traitées par une forme normale de Birkhoff, et ainsi réduites à l’étude d’une famille d’hamiltoniens à un degré de liberté. Corollairement, on obtient une extension de résultats récents de Helffer et Kordyukov à de plus hautes énergies.

This paper is devoted to the classical mechanics and spectral analysis of a pure magnetic Hamiltonian in ℝ 2 . It is established that both the dynamics and the semiclassical spectral theory can be treated through a Birkhoff normal form and reduced to the study of a family of one dimensional Hamiltonians. As a corollary, recent results by Helffer-Kordyukov are extended to higher energies.
