Quantization problem for Lagrangian torus fibrations

Let (X,L)(X,L) be a polarized compact Kähler manifold, with LL a pre-quantum bundle, and let π:XB\pi:X\rightarrow B be a Lagrangian torus fibration. Let ΓX/B(X,L)\Gamma_{X/B}(X,L) denote the space of distributional sections supported on Bohr–Sommerfeld fibers and covariantly constant along the polarization. Quantization problem. The two spaces of wave functions are canonically isomorphic:

ΓX/B(X,L)H0(X,L).\Gamma_{X/B}(X,L)\cong H^0(X,L).

This asks for independence of the resulting quantization from the choice of polarization. The source records proofs in important cases, including flag manifolds and sufficiently large tensor powers under a nondegeneracy hypothesis, but leaves the general statement open.
