# Late time behaviour of cosmological perturbations in a single-brane model

@article{Koyama2004LateTB, title={Late time behaviour of cosmological perturbations in a single-brane model}, author={Kazuya Koyama}, journal={Journal of Cosmology and Astroparticle Physics}, year={2004}, volume={2004}, pages={010-010} }

We present solutions for the late time evolution of cosmological tensor and scalar perturbations in a single-Randall–Sundrum-brane world model. Assuming that the bulk is anti-de Sitter spacetime, the solutions for cosmological perturbations are derived by summing mode functions in the Poincare coordinate. The junction conditions imposed at the moving brane are solved numerically. The recovery of four-dimensional Einstein gravity at late times is shown by solving the five-dimensional…
