| Abstract: | The scalar wave equation in an external gravitational field is considered. In the weakfield approximation, the time-symmetric GREEN 's function is built up via the invariant defining equation to first order in the perturbation parameter. The coefficients of the distributions are represented by four-dimensional FOURIER integrals containing the FOURIER transform of the first-order gravitational potential and KUMMER 's functions. |
