Fukaya–dimer quasi-equivalence conjecture for convex lattice polygons

Let Δ\Delta be a convex lattice polygon containing the origin in its interior. A Laurent polynomial WW has Newton polygon Δ\Delta, and a pair (G,D)(G,D) consists of a consistent dimer model GG and a perfect matching DD whose characteristic polygon is Δ\Delta. The pair determines a directed AA_\infty-category \dirscA\dirscA, while WW determines its Fukaya category \FukW\Fuk W. Fukaya–dimer quasi-equivalence conjecture. There exist such WW and (G,D)(G,D) for which one has a quasi-equivalence

\dirscA\FukW\dirscA \cong \Fuk W

of AA_\infty-categories. This proposes a categorical correspondence between dimer models and Fukaya categories of Laurent polynomials, providing a route toward homological mirror symmetry for toric orbifolds of toric del Pezzo surfaces. The source does not state a resolution of the conjecture.
