1206.0445 (Feng-Jun Xu et al.)

Type II/F-theory Superpotentials and Ooguri-Vafa Invariants of Compact
Calabi-Yau Threefolds with Three Deformations
   [PDF]

Feng-Jun Xu, Fu-Zhong Yang
We construct the generalized hypergeometric GKZ systems for two Calabi-Yau manifolds with three parameters and D-branes wrapped on divisors with single open-string moduli, respectively, and further calculate the D-brane superpotentials which give rise to the flux superpotentials $\mathcal{W}_{GVW}$ of the dual F-theory compactification on the relevant Calabi-Yau fourfolds in the weak decoupling limit. We also compute the Ooguri-Vafa invariants from A-model expansion with mirror symmetry, which are related to the open Gromov-Witten invariants.
