Definition 3.1 Let $(X,J,\omega,\Omega)$ be a Calabi–Yau or almost Calabi–Yau 3-fold, and $f:X\rightarrow B$ a special Lagrangian fibration of $(X,J,\omega,\Omega)$. We shall say that some property of $f$ is generic if for all Kähler forms $\tilde{\omega}$ on $X$ in the same Kähler class as $\omega$ and sufficiently close to $\omega$, there exists close to $f$ a special Lagrangian fibration $\tilde{f}:X\rightarrow B$ of the almost Calabi–Yau 3-fold $(X,J,\tilde{\omega},\Omega)$ with the same property. Examples of properties of $f$ that might or might not be generic are: existence, smoothness, every singular fibre has only finitely many singular points, and so on.
