The tropical parametrization conjecture for the quantum lamination basis
Let -laminations with pinnings on a marked surface form the integral parameter space . Let be the quantum trace map, let be the quantum cluster associated with a vertex of the exchange graph, and let denote the corresponding negative shear-coordinate system.
Tropical parametrization conjecture. The basis is parametrized by tropical points. Namely, for every integral -lamination , the quantum Laurent expression of in the quantum cluster has leading term
with respect to the dominance order.
This is the expected connection between the lamination parametrization and the tropical-point framework underlying quantum Fock--Goncharov duality. The supplied text does not state whether the conjecture has been resolved.
