Singularities of special Lagrangian fibrations and the SYZ Conjecture

Joyce, Dominic (2003) Singularities of special Lagrangian fibrations and the SYZ Conjecture. Communications in Analysis and Geometry, 11 . pp. 859-907.



The SYZ Conjecture explains Mirror Symmetry between Calabi-Yau 3-folds $M$, $\hat{M}$ in terms of special Lagrangian fibrations $f : M \rightarrow B$ and $\hat{f} : \hat{M} \rightarrow B$ over the same base $B$, whose fibres are dual 3-tori, except for singular fibres. This paper studies the singularities of special Lagrangian fibrations.

We construct many examples of special Lagrangian fibrations on open subsets of $\mathbb{C}^3$. The simplest are given explicitly, and the rest use analytic existence results for U(1)-invariant special Lagrangian 3-fold in $\mathbb{C}^3$. We then argue that some features of our examples should also hold for generic special Lagrangian fibrations of (almost) Calabi-Yau 3-folds, and draw some conclusions on the SYZ Conjecture.
