We propose a new, self-consistent and dynamical scenario which gives rise towell-defined initial conditions for five-dimensional brane-world cosmologieswith radion stabilization. At high energies, the five-dimensional effectivetheory is assumed to have a scale invariance so that it admits an expandingscaling solution as a future attractor. The system automatically approaches thescaling solution and, hence, the initial condition for the subsequentlow-energy brane cosmology is set by the scaling solution. At low energies, thescale invariance is broken and a radion stabilization mechanism drives thedynamics of the brane-world system. We present an exact, analytic scalingsolution for a class of scale-invariant effective theories of five-dimensionalbrane-world models which includes the five-dimensional reduction of theHorava-Witten theory, and provide convincing evidence that the scaling solutionis a future attractor.Comment: 17 pages; version accepted for PRD, references adde
