The Coincidence Limit of the Graviton Propagator in de Donder Gauge on
de Sitter Background    [PDF]

E. O. Kahya, S. P. Miao, R. P. Woodard

We explicitly work out the de Sitter breaking contributions to the recent
solution for the de Donder gauge graviton propagator on de Sitter. We also
provide explicit power series expansions for the two structure functions, which
are suitable for implementing dimensional regularization. And we evaluate the
coincidence limit of the propagator.
