Title in Portuguese
Perturbação de spin zero no espaço-tempo de Kerr-Randall-Sundrum
Keywords in Portuguese
Buracos Negros
Modos Quasinormais
Mundo Brana
Relatividade Geral
Superradiância
Abstract in Portuguese
Esta dissertação visa realizar um estudo acerca dos modelos de mundo brana no contexto proposto por Randall e Sundrum. O trabalho focaliza as perturbações de spin 0 no espaço-tempo de Kerr tomado como um mundo brana 4-dimensional. Para isso apresentamos os principais aspectos da Relatividade Geral de Einstein, bem como perturbações em métricas que descrevem buracos negros. Fizemos uma revisão dos modelos de Randall-Sundrum, suas motivações e tentativas de descrever buracos negros na brana. Por m a perturbação escalar da corda negra em rotação (Kerr-Randall-Sundrum) e o fenômeno de super-radiação são analisados.

Abstract in English
This dissertation aims at studying the braneworld models in the context proposed by Randall and Sundrum. The focus is on the spin-0 perturbations in the Kerr space-time as a 4- dimensional braneworld. The work deals the main aspects of Einstein General Relativity as well as perturbations of black holes metrics. We also review the Randall-Sundrum models and their motivations and attempts to describe braneworld black holes. In the end the Kerr-Randall-Sundrum black string scalar perturbation and superradiance are obtained.
