The curvature perturbation in a box

arXiv:0707.0361 · doi:10.1088/1475-7516/2007/12/016

Abstract

The stochastic properties of cosmological perturbations are best defined through the Fourier expansion in a finite box. I discuss the reasons for that with reference the curvature perturbation, and explore some issues arising from it.
