  Special Lagrangian submanifolds are submanifolds of a Calabi-Yau manifold
calibrated by the real part of the holomorphic volume form. In this paper we
use elliptic theory for edge-degenerate differential operators on singular
manifolds to study the moduli space of deformations of special Lagrangian
submanifolds with edge singularities. We obtain a general theorem describing
the local structure of the moduli space. When the obstruction space vanishes
the moduli space is a smooth, finite dimensional manifold.
