Kontsevich–Soibelman conjecture for global torus fibrations

Let BB be a closed Z\mathbb{Z}-affine manifold, let M=TB/TZBM=T^*B/T^*_{\mathbb{Z}}B be the associated symplectic torus fibration, and let OB\mathcal{O}_B be its natural sheaf of Λq\Lambda_q-algebras. Let F(M)\mathcal{F}(M) be the Fukaya category, with gradings and signs defined using the canonical trivialization of KM2\mathcal{K}_M^2 and relative Pin\operatorname{Pin} structures. Kontsevich–Soibelman conjecture. All of F(M)\mathcal{F}(M) embeds cohomologically fully and faithfully into D(OB)\mathcal{D}(\mathcal{O}_B), the derived dg category of OB\mathcal{O}_B-module sheaves.

The preceding theorem gives this embedding for the full subcategory of Lagrangian sections. The conjecture extends that result to all Fukaya-category objects and is presented as an expected global relationship between symplectic geometry and sheaf theory.
