We study the Gepner model description of D-branes in Calabi-Yau manifolds
with singular curves. From a geometrical point of view, the resolution of
singularities leads to additional homology cycles around which branes can wrap.
Using techniques from conformal field theory we address the construction of
boundary states for branes wrapping additional 3-cycles on the resolved
Calabi-Yau manifold. Explicit formulas are provided for Z_2 singular curves.Comment: 25 pages, late
