Poincaré duality for $L^p$ cohomology on subanalytic singular spaces

We 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. In the case where $p$ is large, we show that $L^p$ cohomology is dual to intersection homology. As a consequence, we can deduce that the $L^p$ cohomology is Poincaré dual to $L^q$ cohomology, if $p$ and $q$ are Hölder conjugate to each other and $p$ is sufficiently large.
