The Weyl tensor two-point function in de Sitter spacetime
Spyros S. Kouris
We present an expression for the Weyl-Weyl two-point function in de Sitter spacetime, based on a recently calculated covariant graviton two-point function with one gauge parameter.…
The covariant graviton propagator in de Sitter spacetime
Atsushi Higuchi, Spyros S. Kouris
We consider the covariant graviton propagator in de Sitter spacetime in a gauge with two parameters, alpha and beta, in the Euclidean approach. We give an explicit form of the prop…
On the scalar sector of the covariant graviton two-point function in de Sitter spacetime
Atsushi Higuchi, Spyros S. Kouris
We examine the scalar sector of the covariant graviton two-point function in de Sitter spacetime. This sector consists of the pure-trace part and another part described by a scalar…
Large-distance behaviour of the graviton two-point function in de Sitter spacetime
A. Higuchi, S. S. Kouris
It is known that the graviton two-point function for the de Sitter invariant "Euclidean" vacuum in a physical gauge grows logarithmically with distance in spatially-flat de Sitter…
