Heat kernel asymptotics for roots of generalized Laplacians
Autoren: Christian Bär, Sergiu Moroianu (2003)
We describe the heat kernel asymptotics for roots of a Laplace type operator Δ on a closed manifold. A previously known relation between the Wodzicki residue of Δ and heat trace asymptotics is shown to hold pointwise for the corresponding densities.
