Intersection homology theory provides a way to obtain generalized Poincaré duality, as well as a signature and characteristic classes, for singular spaces. For this to work, one has had to assume however that the space satisfies the so-called Witt condition. Extending Intersection Homology Type Invariants to Non-Witt Spaces.

CHAPTER 1 Introduction 1. History The question of extending Poincare duality to a suitable kind of homology on spaces . History The question of extending Poincare duality to a suitable kind of homology on spaces more general than manifolds was attacked by Goresky and MacPherson, us- ing sheaf-theoretic methods, in their fundamental paper. They construct a differential complex of sheaves IC (X) defined on a pseudomanifold X and de- pending on a parameter p, the so-called perversity. In that case, the canonical morphism IC ^ - IC is a quasi-isomorphism and again lQ h{X) is self-dual.
