Poincaré duality for spaces with isolated singularities
arXiv:1507.07407 · doi:10.1007/s00229-016-0884-5
Abstract
In this paper we assign, under reasonable hypothesis, to each pseudomanifold with isolated singularities a rational Poincaré duality space. These spaces are constructed with the formalism of intersections spaces defined by Markus Banagl and are indeed related to them in the even dimensional case.
