Mode-sum construction of the covariant graviton two-point function in the Poincaré patch of de Sitter space

Markus B. Fröb, Atsushi Higuchi, William C. C. Lima

We construct the graviton two-point function for a two-parameter family of linear covariant gauges in n-dimensional de Sitter space. The construction is performed via the mode-sum…
