Math. 160, 239-265 (1998).
From the paper: Mirror symmetry of Calabi-Yau manifolds has been playing a central role in revealing non-perturbative aspects of the type II string vacua, i.e., the moduli spaces for a family of Calabi-Yau manifolds. Since the success in determining the quantum geometry on the IIA moduli space made by P. Candelas, X. C. de la Ossa, P. S. Green, L. Parkes [in: Essays on mirror manifolds, 31-95 (1992; Zbl 0826.32016)], there has been much progress and a lot of communications between physics and mathematics on these topics.
In this article we present a detailed analysis of the GKZ hypergeometric systems [see I. M. Gel’fand, A. V. Zelevinskij and M. M. Kapranov, Funct. Anal. Appl. 23, No. 2, 94-106 (1989); translation from Funkts. Anal. Prilozh. 23, No. 2, 12-26 (1989; Zbl 0721.33006)] in the context of mirror symmetry of Calabi-Yau hypersurfaces in toric varieties. As an application, we will derive a concise formula for the prepotential about large complex structure limits.
