http://www.map.mpim-bonn.mpg.de/Intersection_form WebWe investigate the problem of Poincaré duality for L^p differential forms on bounded subanalytic submanifolds of \mathbb {R}^n (not necessarily compact). We show that, when p is sufficiently close to 1 then the L^p cohomology of such a submanifold is isomorphic to its singular homology.
