(Special Lagrangian fibration) There exist moment coordinates $\tilde{\mu}_{1},\tilde{\mu}_{2}$ for the $T^{2}$ action on $\omega^{+}$. The special Lagrangian fibration

(3.14)

$$M^{+}_{\nu}\xrightarrow{(\tilde{\mu}_{1},\tilde{\mu}_{2},\text{Im}\eta)}\mathbb{R}^{3}$$

is proper over $\{|(\tilde{\mu}_{1},\tilde{\mu}_{2},\text{Im}\eta)|_{a}^{\prime}\leq\frac{1}{2}A^{1/2}e^{\nu}\}\subset\mathbb{R}^{3}$ where the generic fibre is topologically $T^{3}$. The critical point set is $\bigcup_{i,j\in\{0,1,2\}}\{\tilde{Z}_{i}=\tilde{Z}_{j}=0\}$ and the discriminant locus is contained in $\mathfrak{D}$. The monodromy of the fibration and the topology of the central singular fibre agrees with the Gross-Ruan prediction in Section 1.1.3.
