Abstract
Let (X,g) be a compact Riemannian stratified space with simple edge singularity. Thus a neighborhood of the singular stratum is a bundle of truncated cones over a lower-dimensional compact smooth manifold. We calculate the various polynomially weighted de Rham cohomology spaces of X, as well as the associated spaces of harmonic forms. In the unweighted case, this is closely related to recent work of Cheeger and Dai. Because the metric g is incomplete, this requires a consideration of the various choices of ideal boundary conditions at the singular set. We also calculate the space of L2 harmonic forms for any complete edge metric on the regular part of X.
