D-brane Superpotentials and Geometric Invariants in Complete Intersection Calabi-Yau Manifolds
Xuan Li, Yuan-Chun Jing, Fu-Zhong Yang
By blowing up the ambient space along the curve wrapped by B-branes, we study the brane superpotentials and Ooguri-Vafa invariants on complete intersections Calabi-Yau threefolds.…

Open Topological String Amplitudes on Calabi-Yau Threefolds by Extended Holomorphic Anomaly Equation
Xuan Li, Yuan-Chun Jing, Fu-Zhong Yang
In this paper, we study the open topological string amplitudes on Calabi-Yau threefolds by the extended holomorphic anomaly equation. The disk two-point function determined by the…
