Stationary GW/PT descendent correspondence beyond toric threefolds

Let XX be a nonsingular projective 3-fold, let γiH2(X,C)\gamma_i\in H^{\geq 2}(X,\mathbb{C}), and let k=(k1,,kl)\vec{k}=(k_1,\ldots,k_l) be a vector of non-negative integers. Define the modified Gromov–Witten insertions Hk1(γ1)Hkl(γl)\overline{\mathrm{H}_{k_1}(\gamma_1)\dots\mathrm{H}_{k_l}(\gamma_l)}, and let d=βc1d=\int_\beta c_1. After the change of variables q=eiu-q=e^{iu},

Stationary GW/PT correspondence conjecture.

Hk1(γ1)Hkl(γl)βGW=qd/2Hk1PT(γ1)HklPT(γl)βPT.\Big\langle\overline{ \mathrm{H}_{k_1}(\gamma_1)\dots \mathrm{H}_{k_l}(\gamma_l)} \Big\rangle_{\beta}^{\mathsf{GW}}=q^{-d/2}\Big\langle \mathrm{H}^{\mathsf{PT}}_{k_1}(\gamma_1)\dots \mathrm{H}^{\mathsf{PT}}_{k_l}(\gamma_l) \Big\rangle_{\beta}^{\mathsf{PT}}.

The theorem preceding the conjecture proves this correspondence for nonsingular projective toric 3-folds and classes of degree at least 22. The conjecture asserts that the toric restriction is unnecessary, while retaining the stationary insertion hypothesis.
