Give the smooth subset of a normal singular complex projective surface the metric induced from the ambient projective space. The L2 cohomology of this incomplete manifold is isomorphic to the surface's intersection cohomology, which has a natural Hodge decomposition. This paper identifies Dolbeault complexes whose d -closed and 3-coclosed forms represent the classes of pure type in the corresponding Hodge decomposition of L2 cohomology.
