Variations on Poincaré duality for intersection homology
Martintxo Saralegi-Aranguren, Daniel Tanré
Intersection homology with coefficients in a field restores Poincaré duality for some spaces with singularities, as pseudomanifolds. But, with coefficients in a ring, the behaviour…
Poincaré duality, cap product and Borel-Moore intersection Homology
Martintxo Saralegi-Aranguren, Daniel Tanré
Using a cap product, we construct an explicit Poincaré duality isomorphism between the blown-up intersection cohomology and the Borel-Moore intersection homology, for any commutati…
Blown-up intersection cochains and Deligne's sheaves
David Chataur, Martintxo Saralegi-Aranguren, Daniel Tanré
In a series of papers the authors introduced the so-called blown-up intersection cochains. These cochains are suitable to study products and cohomology operations of intersection c…
