We derive an asymptotic expansion analogous to the Hadamard expansion for powers of advanced/retarded Green's operators associated to a normally hyperbolic operator P, as well as expansions for advanced/retarded Green's operators associated to P-z for z∈ ℂ. These expansions involve the same Hadamard coefficients as the original Hadamard expansion.
