چکیده

Motivated by a conjecture of Lian and Yau concerning the mirror map in string theory [LY1, ICMP], we determine when the mirror map qseries of certain elliptic curve and K3 surface families are Hauptmoduln (genus zero modular functions). Our geometric criterion for modularity characterizes orbifold uniformization properties of their Picard-Fuchs equations, effectively demystifying the mirror-moonshine phenomenon. A longer, more comprehensive treatment of these results can be found in [Dor2]. For a detailed look at several explicit examples of this phenomenon, see the article by Verrill and Yui in this volume [VY].

Mirror Symmetry, Mirror Map and Applications to Calabi-Yau Hypersurfaces

Mirror Symmetry, Picard-Fuchs equations and instanton corrected Yukawa couplings are discussed within the framework of toric geometry. It allows to establish mirror symmetry of Calabi-Yau spaces for which the mirror manifold had been unavailable in previous constructions. Mirror maps and Yukawa couplings are explicitly given for several examples with two and three moduli.

Picard-fuchs Equations and Mirror Maps for Hypersurfaces

We describe a strategy for computing Yukawa couplings and the mirror map, based on the Picard-Fuchs equation. (Our strategy is a variant of the method used by Candelas, de la Ossa, Green, and Parkes [5] in the case of quintic hypersurfaces.) We then explain a technique of Griffiths [14] which can be used to compute the Picard-Fuchs equations of hypersurfaces. Finally, we carry out the computati...

Mirror Symmetry of Calabi-Yau Manifolds and Flat Coordinates

We study mirror symmetry of Calabi-Yau manifolds within the framework of the Gauss-Manin system. Applying the flat coordinates to the Gauss-Manin system for the periods, we derive differential equations for the mirror map in addition to the ordinary Picard-Fuchs equations for the periods. These equations are obtained for a class of one-parameter models and a two-parameter model of Fermat type C...

Open string mirror maps from Picard- Fuchs equations on relative cohomology

A method for computing the open string mirror map and superpotential, using an extended set of PicardFuchs equations, is presented. This is based on techniques used by Lerche, Mayr and Warner in [4], [1]. For X a toric hypersurface and Y a hypersurface in X, the mirror map and superpotential are written down explicitly. As an example, the case of KP2 is worked out and shown to agree with the li...

Towards Open String Mirror Symmetry for One–Parameter Calabi–Yau Hypersurfaces

This work is concerned with branes and differential equations for one–parameter Calabi–Yau hypersurfaces in weighted projective spaces. For a certain class of B–branes we derive the inhomogeneous Picard–Fuchs equations satisfied by brane superpotential. In this way we arrive at a prediction for the real BPS invariants for holomorphic maps of worldsheets with low Euler characteristics, ending on...
