For compact Calabi-Yau geometries with D5-branes I discuss N=1 superpotentials
depending on both open- and closed-string fields. I explain how to compute
the open/closed Picard-Fuchs differential equations, which control D5-brane deformations
and complex structure deformations of the Calabi-Yau space. The solutions of the
differential equations encode the effective superpotential in flat coordinates, which in
turn is the generating function of certain disk invariants. The presented techniques are
demonstrated with an explicit example of a compact D5-brane in a Calabi-Yau hyperplane
geometry.
