Abstract The demands of gauge field theories, quantum theory in external gauge and gravitational backgrounds, and quantum gravity have spurred intense study of the asymptotic heat kernel expansion for nonminimal differential operators on curved manifolds in the presence of a gauge field. There are several computer programs for calculating the coefficients in an expansion of the heat kernel. When applied to the nonminimal operator these programs appeared to be able to compute no more than the… CONTINUE READING
