Analytic continuation of Saito–Givental theories between Gepner and large-complex-structure points

Let $W^{\vee}_0=W^{\vee}$ be the Gepner point and $W^{\vee}_{\infty}=\prod_i x_i$ the large complex structure point in the deformation space of $W^{\vee}$. Let the corresponding Saito–Givental theories be defined near these two points. Gepner/large-complex-structure continuation. The Saito–Givental theories at $W^{\vee}_0$ and $W^{\vee}_{\infty}$ are related by analytic continuation and a symplectic transformation. This conjectural relation is intended to connect the Landau–Ginzburg and Calabi–Yau descriptions through the two distinguished points; the source gives no general proof.
