Mirror symmetry for Calabi-Yau manifold

We study with the help of mirror symmetry, the quantum geometry of the Kahler-class parameters of a Calabi-Yau manifold. Our interest lies in the structure of the moduli space, which is considerably richer when there are two parameters. We describe the intrinsic structure of the point in the moduli space that corresponds to the large complex structure or classical limit.
