Ooguri–Vafa integrality conjecture for the chromatic Lagrangian superpotential

Let LL be a Lagrangian with boundary SΓS_\Gamma, let AA be a choice of phase and framing, and let WΓ(A)W_\Gamma^{(A)} be a primitive function whose graph of the differential gives the lifted moduli space of the Lagrangian. For coordinates (x1,,xg)(x_1,\ldots,x_g) determined by a basis of H1(L)H_1(L), write xd=x1d1xgdgx^d=x_1^{d_1}\cdots x_g^{d_g}. Ooguri–Vafa integrality conjecture. The superpotential WΓ(A)W_\Gamma^{(A)} is the generating function for holomorphic disk invariants of LL in framing AA, with expansion

WΓ(A)(x1,,xg)=dZ0g{0}nd(A)Li2(xd),W_\Gamma^{(A)}(x_1,\ldots,x_g)=\sum_{d\in\mathbb{Z}_{\geq 0}^g\setminus\{0\}}n_d^{(A)}\operatorname{Li}_2(x^d),

where

Li2(x)=n0xnn2\operatorname{Li}_2(x)=\sum_{n\geq 0}\frac{x^n}{n^2}

and nd(A)n_d^{(A)} are integers. This conjecture extends the Ooguri–Vafa, Aganagic–Vafa, and Aganagic–Klemm–Vafa disk-counting framework to the chromatic Lagrangian setting; a rigorous definition of the relevant open Gromov–Witten invariants remains in development.
