摘要: We study the fourth order action of comoving curvature perturbation in an inflationary universe to understand more systematically de Sitter limit nonlinear cosmological theory. derive gauge, and show that it vanishes sufficiently fast limit. By studying limit, we then extrapolate n'th discuss slow-roll n-point correlation function.
