dc.descriptionWe review the doubly gauge invariant formalism of cosmological perturbations in the Randall-Sundrum brane world. This formalism leads to four independent equations describing the evolution of scalar perturbations. Three of these equations are differential equations written in terms of gauge invariant variables on the brane only, and the other is an integro-differential equation describing non-locality due to bulk gravitational waves. At low energy the evolution of the scalar-type cosmological perturbations in the brane-world cosmology differs from that in the standard cosmology only by non-local effects due to bulk gravitational waves.
