A Characterization of the Heat Kernel Coefficients

Abstract

We consider the asymptotic expansion of the heat kernel of a generalized Laplacian for t0+t\to 0^+ and characterize the coefficients aka_k of this expansion by a natural intertwining property. In particular we will give a closed formula for the infinite order jet of these coefficients on the diagonal in terms of the local expressions of the powers of the given generalized Laplacian in normal coordinates.
