Abstract
The Laplacian acting onk-forms on a manifold with isolated conic singularities is not in general an essentially self-adjoint operator. The heat kernels for self-adjoint extensions of the Laplacian on these metric spaces are described as functions conormal to a manifold with corners. The heat kernel for a given self-adjoint extension is constructed from the Friedrichs heat kernel. The terms in the difference of the heat trace expansions are shown to supply information parametrizing the extension.
