Perturbations of an expanding brane. / Andrew Buxton

Swansea University Author: Andrew Buxton

Abstract

Motivated by the study of the cosmology of brane-worlds we begin by inducing vacuum decay in a 4+1 space-time assuming that the most likely configuration possesses spherical symmetry, and interpret the wall between the two vacua as a thick brane. We then set out to deduce the spectrum of perturbatio...
