Semiclassical inverse spectral theory for singularities of focus-focus type

Mathematical Physics 2015-06-15 v1 math.MP Symplectic Geometry Spectral Theory

Abstract

We prove, assuming that the Bohr-Sommerfeld rules hold, that the joint spectrum near a focus-focus critical value of a quantum integrable system determines the classical Lagrangian foliation around the full focus-focus leaf. The result applies, for instance, to h-pseudodifferential operators, and to Berezin-Toeplitz operators on prequantizable compact symplectic manifolds.
