Open orbifold mirror symmetry conjecture for Gromov–Witten potentials

Let XX be a toric Calabi–Yau threefold and X\mathfrak{X} its orbifold phase. Let {tiX}\{t_i^X\} and {tiX}\{t_i^{\mathfrak{X}}\} denote their quantum parameters, with compact flat coordinates t^iX,t^iX\hat t_i^X,\hat t_i^{\mathfrak{X}} and non-compact coordinates t~iX,t~iX\tilde t_i^X,\tilde t_i^{\mathfrak{X}}. Suppose the compact coordinates and prepotentials are related by

(t^iXF0X/t^iX)=(AB\CD)(t^iXF0X/t^iX),\begin{pmatrix}\hat t_i^X\\ \partial\mathcal{F}_0^X/\partial\hat t_i^X\end{pmatrix}= \begin{pmatrix}A&B\C&D\end{pmatrix} \begin{pmatrix}\hat t_i^{\mathfrak{X}}\\ \partial\mathcal{F}_0^{\mathfrak{X}}/\partial\hat t_i^{\mathfrak{X}}\end{pmatrix},

and the open parameters satisfy xj=wjkqkrkx_j=w_j\prod_kq_k^{r_k}. Let Wh(g)W_h^{(g)} be the open correlators of XX, with W1(0)=dλXW_1^{(0)}=d\lambda_X when (g,h)=(0,1)(g,h)=(0,1), and let M=(AB\CD)M=\begin{pmatrix}A&B\C&D\end{pmatrix} be the corresponding change-of-basis matrix. Define the transformed correlators Wh(g)\mathcal{W}_h^{(g)} as in the source for 2g+h>12g+h>1, and set W~1(0)=W1(0)\widetilde W_1^{(0)}=W_1^{(0)}.

Open orbifold mirror symmetry conjecture. The open orbifold potentials Fg,h(X,L)F_{g,h}^{(\mathfrak{X},\mathcal{L})} are given, after applying the orbifold open and closed mirror maps, by

Wh(g)(p1,,ph)dp1p1dphph.\int\mathcal{W}_h^{(g)}(p_1,\ldots,p_h)\frac{dp_1}{p_1}\dots\frac{dp_h}{p_h}.

The conjecture proposes that the symplectic change-of-basis data relating the large-radius and orbifold points suffice to reconstruct open Gromov–Witten potentials of the orbifold from those of XX. The source gives no resolution status, and the transformation defining Wh(g)\mathcal{W}_h^{(g)} is referenced but not reproduced here.
