The dimer model realization conjecture for Laurent polynomials

At least 15 years old · documented by

Let Δ\Delta be a lattice polygon containing the origin in its interior. Choose a Laurent polynomial WW whose Newton polygon coincides with Δ\Delta, together with a distinguished basis of vanishing cycles on W−1(0)W^{-1}(0). For the argument map

Arg⁡:(C×)2→R2/Z2↓↓(x,y)↦12π(arg⁡x,arg⁡y),\begin{array}{cccc} \operatorname{Arg}: & (\mathbb{C}^{\times})^2 & \to & \mathbb{R}^2 / \mathbb{Z}^2 \\ & \downarrow & & \downarrow \\ & (x,y) & \mapsto & \dfrac{1}{2\pi}(\arg x,\arg y), \end{array}

Dimer model realization conjecture. For a suitable choice of WW and distinguished basis, there is a bicolored graph YY on W−1(0)W^{-1}(0) such that an edge of YY corresponds to an intersection of vanishing cycles, a node of YY corresponds to a holomorphic disk bounded by vanishing cycles, the color of a node corresponds to the sign of the associated A∞A_\infty-operation, and the image of YY under the argument map is a consistent dimer model GG. The order on the distinguished basis gives a perfect matching DD, and the characteristic polygon of (G,D)(G,D) coincides with Δ\Delta.

This conjecture predicts a direct geometric realization of consistent dimer models and perfect matchings from the vanishing-cycle data of a Laurent polynomial. It is motivated by the proposed relationship between dimer models and mirror symmetry; the supplied source does not state whether the conjecture is open or resolved.
