Semiclassical equivalence conjecture for geometric quantizations

Let (M,ω)(M,\omega) be a closed symplectic manifold. A geometric quantization is a sequence of maps {Tk:C(M)L(Hk)}kN\{T_k:C^\infty(M)\to\mathcal{L}(H_k)\}_{k\in\mathbb{N}} satisfying the geometric quantization axioms, where HkH_k are Hilbert spaces. Semiclassical equivalence conjecture. Two geometric quantizations of (M,ω)(M,\omega) associated with sequences of Hilbert spaces of the same dimension are semiclassically equivalent; that is, after conjugation by a sequence of unitary operators, their quantization maps agree to order O(1/k)O(1/k) on every fixed smooth function. This generalizes the established equivalence results for the sphere and torus to arbitrary closed symplectic manifolds, while the general case remains open.
