On homological mirror symmetry of toric Calabi-Yau three-folds

Abstract

We use Lagrangian torus fibrations on the mirror $X$ of a toric Calabi-Yau threefold $\check{X}$ to construct Lagrangian sections and various Lagrangian spheres on $X$. We then propose an explicit correspondence between the sections and line bundles on $\check{X}$ and between spheres and sheaves supported on the toric divisors of $\check{X}$. We conjecture that these correspondences induce an embedding of the relevant derived Fukaya category of $X$ inside the derived category of coherent sheaves on $\check{X}$.
