RESUMO
In this dissertation we investigate some aspects related with normal modes for scalar fields perturbations of a Schwarzshild-de Sitter black hole. The role played by the cosmological constant A on the reflection and transmission coefficients is studied and analyzed. We also study the Casimir energy density for a massless scalar field confined between two nearby parallel plates in the spacetime of Schwarzschild-de Sitter in the weak field approximation. The role played by the cosmological constant in this scenario is emphasized.
