Trace asymptotics conjecture for geometric quantizations

About 6 years old · traced to

Let (M,ω)(M,\omega) be a closed symplectic manifold, and let {Tk:C∞(M)→L(Hk)}k∈N\{T_k:C^\infty(M)\to\mathcal{L}(H_k)\}_{k\in\mathbb{N}} be a geometric quantization satisfying the trace axiom and star product axiom. Let tr⁡ℏ\operatorname{tr}_{\hbar} denote the canonical trace, with k=1/ℏk=1/\hbar. Trace asymptotics conjecture. For all f∈C∞(M)f\in C^\infty(M) and m∈Nm\in\mathbb{N}, one has the asymptotic expansion

tr⁡ Tk(f)=tr⁡ℏ(f)+O(1/km)\operatorname{tr}\,T_k(f)=\operatorname{tr}_{\hbar}(f)+O(1/k^m)

as k=1/ℏ→+∞k=1/\hbar\to+\infty. The conjecture asserts agreement with the canonical trace to every order; it was established for Berezin–Toeplitz quantizations of closed Kähler manifolds by Hawkins, so the source's cited case is solved while the general statement is not resolved here.
