Assumption 8.1 Let $\mathbin{\mathbb{Z}}$ act on $\mathbin{\mathbb{C}}^{3}$ by $(z_{1},z_{2},z_{3})\,{\mathrel{\mathop{\kern 0.0pt\mapsto}\limits^{n}}}\,(z_{1},z_{2},z_{3}+2\pi n)$ for $n\in\mathbin{\mathbb{Z}}$. Define $U=\bigl\{(z_{1},z_{2},z_{3}\!+\!2\pi\mathbin{\mathbb{Z}})\in\mathbin{\mathbb{C}}^{3}/\mathbin{\mathbb{Z}}:\mathop{\rm Im}(z_{1}z_{2})\in[-\pi,\pi]\bigr\}$. Consider a special Lagrangian fibration $f:U\rightarrow\mathbin{\mathbb{R}}^{3}$, with fibres $N_{a,b,c}=f^{-1}(a,b,c)$. Suppose that $f$ satisfies parts (i)–(viii) of Assumption 7.1.
