Cosmological Perturbation Theory in Slow-Roll Spacetimes
arXiv:0804.4296 · doi:10.1103/PhysRevLett.101.111101
Abstract
We present a gauge invariant argument that a nonlocal measure of second-order metric and matter perturbations dominate that of linear fluctuations in its effect on the gravitational field in 'slow-rolling' spacetimes.
