Sémin. Équ. Dériv. Partielles, Éc. Polytech., Cent. Math., Palaiseau 1990-1991, No.XXIII, 15 p. (1991).
Summary: We describe the asymptotic structure of the spectrum and the resonances of the equation \(-\psi_{xx}+V(\varepsilon x,x)\psi=E\psi\), where \(V(\xi,x)\) is a periodic function of the second variable and \(\varepsilon\) is a small parameter.
