General perversities and L^2 de Rham and Hodge theorems for stratified pseudomanifolds
Abstract
Given a compact stratified pseudomanifold with a Thom-Mather stratification and a class of riemannian metrics over its regular part, we study the relationships between the de Rham and Hodge cohomology and the intersection cohomology of associated to some perversities. More precisely, to a kind of metric which we call \emph{quasi edge with weights}, we associate two general perversities in the sense of G. Friedman, and its dual . We then show that the absolute Hodge cohomology is isomorphic to the maximal de Rham cohomology and this is in turn isomorphic to the intersection cohomology associated to the perversity . Moreover we prove that the relative Hodge cohomology is isomorphic to the minimal de Rham cohomology and this is in turn isomorphic to the intersection cohomology associated to the perversity .
