Singular decompositions of a cap product
David Chataur, Martintxo Saralegi-Aranguren, Daniel Tanré
In the case of a compact orientable pseudomanifold, a well-known theorem of M. Goresky and R. MacPherson says that the cap product with a fundamental class factorizes through the i…
Poincaré duality with cap products in intersection homology
David Chataur, Martintxo Saralegi-Aranguren, Daniel Tanré
For having a Poincaré duality via a cap product between the intersection homology of a paracompact oriented pseudomanifold and the cohomology given by the dual complex, G. Friedman…
Intersection Homology. General perversities and topological invariance
David Chataur, Martintxo Saralegi-Aranguren, Daniel Tanré
Topological invariance of the intersection homology of a pseudomanifold without codimension one strata, proven by Goresky and MacPherson, is one of the main features of this homolo…
