Comportement semi-classique du spectre des hamiltoniens quantiques elliptiques
Annales de l'Institut Fourier, Tome 31 (1981) no. 3, pp. 169-223.

Dans cet article nous généralisons les résultats obtenus par J. Chazarain sur le spectre d’opérateurs de Schrödinger P(h)=h 2 2Δ+V lorsque h0. Nous étendons ses résultats aux opérateurs pseudo-différentiels globalement elliptiques d’ordre m>0.

In this article we extend results obtained by J. Chazarain about the spectrum of Schrödinger operators: P(h)=h 2 2Δ+V when h>0 approach 0. We obtain the same results for globally elliptic pseudodifferential operators of order m>0.
