D-branes on Calabi-Yau Manifolds and Superpotentials
arXiv:hep-th/0203173 · doi:10.1007/s00220-004-1091-x
Abstract
We show how to compute terms in an expansion of the world-volume superpotential for fairly general D-branes on the quintic Calabi-Yau using linear sigma model techniques, and show in examples that this superpotential captures the geometry and obstruction theory of bundles and sheaves on this Calabi-Yau.
