New Perspectives on Poincare Duality for Singular Spaces. Markus Banagl (Universitat Heidelberg, Germany) Intersection homology provides a generalized form of Poincare duality for singular spaces. After reviewing this, we shall contrast intersection homology with a new homology associated to singular spaces, which also enjoys Poincare duality but is not isomorphic to intersection homology. The new theory is expected to be definable on a smaller class of singular spaces than intersection homology, but when it is defined, it has a richer algebraic structure, for instance a perversity-internal cup product. We will discuss the new theory, at least for isolated singularities, from several different angles, such as a homotopy theoretic one, which constructs the theory as the ordinary homology of certain cell complexes, and a more analytic one, constructing it via a certain complex of smooth differential forms. The relevance of the new theory vis-a-vis type II string theory will also be briefly indicated.
