D-brane Superpotentials and Ooguri-Vafa Invariants of Compact Calabi-Yau Threefolds
Feng-Jun Xu, Fu-Zhong Yang
We calculate the D-brane superpotentials for two non-Fermat type compact Calabi-Yau manifolds which are the hypersurfaces of the weighed projective spaces in type II string theory.…

Ooguri-Vafa Invariants and Off-shell Superpotentials of Type II/F-theory compactification
Feng-Jun Xu, Fu-Zhong Yang
In this paper, we make a further step of \cite{Feng} and calculate off-shell superpotential of two Calabi-Yau manifold with three parameters by integrating the period of subsystem.…

Off-shell D-Brane/F-Theory Effective Superpotentials and Ooguri-Vafa Invariants of Several Compact Calabi-Yau Manifolds
Shi Cheng, Feng-Jun Xu, Fu-Zhong Yang
According to the generalized GKZ system for CY manifold with brane and the open-closed Mirror map, We calculate the off-shell D-Brane/F-Theory effective superpotentials and Ooguri-…
