Abstract
In classical PDE theory, Widder's theorem gives a representation for nonnegative solutions of the heat equation on . We show that an analogous theorem holds for local weak solutions of the canonical "heat equation" on a symmetric local Dirichlet space satisfying a local parabolic Harnack inequality.
