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…
Symmetric Lie models of a triangle
Urtzi Buijs, Yves Félix, Aniceto Murillo +1
R. Lawrence and D. Sullivan have constructed a Lie model for an interval from the geometrical idea of flat connections and flows of gauge transformations. Their model supports an a…
