Abstract

We investigate the localization of a massive scalar for both dS and AdS branes, where the scalar mass is varied from the massive-particle region to the tachyon region. We find that the eigenmass m of the localized mode satisfies a simple relation m² = cM² with a positive constant c for the dS brane, and m² = c₁M² + CM₂ with positive constants c₁ and c₂ for the AdS brane. We discuss the relation of these results to the stability of the brane and also some cosmological problems.
