Ghosts in asymmetric brane gravity and the decoupled stealth limit
Kazuya Koyama, Antonio Padilla, Fabio P Silva
We study the spectrum of gravitational perturbations around a vacuum de Sitter brane in a 5D asymmetric braneworld model, with induced curvature on the brane. This generalises the…

Non-linear interactions in a cosmological background in the DGP braneworld
Kazuya Koyama, Fabio P Silva
We study quasi-static perturbations in a cosmological background in the Dvali-Gabadadze-Porrati (DGP) braneworld model. We identify the Vainshtein radius at which the non-linear in…
