Bohr-Sommerfeld conditions for integrable systems with critical manifolds of focus-focus type

Abstract: We present a detailed study, in the semi-classical regime h → 0, of microlocal properties of systems of two commuting h-pseudo-differential operators P 1 (h), P 2 (h) such that the joint principal symbol p = (p 1 , p 2 ) has a special kind of singularity called a focus-focus singularity. Typical examples include the quantum spherical pendulum or the quantum Champagne bottle.In the spirit of Colin de Verdière and Parisse [11,12,13], we show that such systems have a universal behavior described by singular quant… Show more

“…In the usual Bohr Sommerfeld conditions on a cotangent phase space, β E + 1 2 δ E is replaced by a sum of two closed forms, the first one is obtained as β E from the subsymbols and the second one is the Maslov form (cf. theorem 4.5.8 of [10]). …”

“…Indeed, we can prove that the microsupport of (v α ) is a subset of h −1 0 (C) (cf. proposition 4.4.6 of [10] for a proof in the case of pseudodifferential operators with a small parameter that we can easily adapt to our situation).…”

“…; avec l'argument de la dimension 1 on peut montrer ( [38], [39], [40]) qu'il y a une unique faon de prolonger la solution φ 1 le long de la courbe enévitant la singularité pour arriver sur l'ouvert U 4 ; la solution finale φ 1 diffère alors de la solution φ 4 par un facteur de phase ( [38], [39], [40]) : φ 1 = e iS + (E)/h φ 4 où la fonctions S + admet un développement asymptotique en puissance de h : S + (E) = ∞ i=0 S + j (E)h j avec des coefficients S + j qui sont C ∞ par rapportà la variable E. De la même façon on a que φ 2 = e iS − (E)/h φ 3 avec aussi une fonctions S − ayant un développement asymptotique en puissance de h :…”
