This analysis demonstrates how tropical curves can be related to special Lagrangian submanifolds, suggesting a profound connection in geometry.
We show that any locally planar tropical curve Γ⊂ Rⁿ (with unit edge weights) can be realized as the limit of the rescaled moment map images of a family of special Lagrangian submanifolds in T^*Tⁿ with respect to the Euclidean structure. This is based on a gluing construction that matches special Lagrangian local models to the combinatorics of $Γ$, thereby establishing a direct link between tropical geometry and special Lagrangian geometry.
