Abstract. On a smoothly stratified space, we identify intersection cohomology of any given perversity with an associated weighted L 2 cohomology for iterated fibred cusp metrics on the smooth stratum.Résumé. Sur une variété stratifiée admettant une résolution par une variétéà coins fibrés, on identifie la cohomologie d'intersection, pour une perversité donnée, avec la cohomologie L 2à poids d'une métriqueà cusps fibrés itérée définie sur la strate lisse.The Hodge theorem for smooth compact manifolds establishes an important link between two analytic invariants of a manifold, the vector space of (L 2 ) harmonic forms over the manifold and the (L 2 ) cohomology, and a topological invariant of the manifold, the cohomology with real coefficients, calculated using cellular, simplicial or smooth deRham theory. The purpose of this paper is to show that by considering instead a natural class of complete metrics called iterated fibred cusp metrics, one can circumvent the analytical difficulties due to the incompleteness of iterated conical metrics, opening in this way a simpler and more direct route towards a description of intersection cohomology in terms of harmonic forms. More precisely, for any smoothly stratified space, X, we obtain a Hodge theorem identifying the intersection cohomology of X of a given perversity with a weighted L 2 cohomology of the regular set X \ X sing , endowed with a complete iterated fibred cusp metric which near the singular strata has hyperbolic cusp type behaviour on the link. The Kodaira decomposition theorem tells us that when the weighted L 2 cohomology with respect to some metric is finite dimensional, it is isomorphic to the space of weighted L 2 harmonic forms, so as a consequence, we also get an isomorphism to the space of weighted L 2 harmonic forms for this metric. By reference to the theory of Hilbert complexes, see [3], we additionally obtain the corollary that the weighted Hodge Laplacian associated to such a metric and weight is Fredholm as an unbounded operator on the space of weighted L 2 differential forms. In particular, when X is a Witt space, we show that the unweighted L 2 cohomology on X with respect to a complete iterated fibred cusp metric is isomorphic to the (unique) middle perversity intersection cohomology of X.Our Hodge theorem can be seen as a natural generalization, from the setting of smooth Kähler manifolds to the singular Witt setting, the result by Timmerscheidt in which the
