Abstract in Portuguese
Nesta tese, nós estabelecemos algumas correspondências entre a dinâmica de campos escalares clássicos em certos espaço-tempos de fundo e duais algébricos apropriados. Os cenários estudados incluem soluções tipo buraco negro com constante cosmológica não nula e os espaçostempos conhecidos como geometrias quase-extremas. Com base em várias propostas na literatura, associamos certos elementos próprios da dinâmica escalar a uma representação apropriada de uma álgebra relacionada com a invariância das equações de movimento escalar sob transformações conformes. Em particular, nós associamos representações de peso maior de dimensão infinita da álgebra sl(2,R) com modos e frequências quase-normais de campo escalar em geometrias quase-extremas e geometrias assintóticamente Anti de Sitter.

Abstract in English
In this thesis, we establish some correspondences between dynamics of classical scalar fields in certain background spacetimes and appropriate algebraic duals. The scenarios studied include black hole solutions with non-zero cosmological constant and the spacetimes known as near extremal geometries. Based on several proposals in the literature, we associate certain elements proper to scalar perturbative dynamics to an appropriated representation of an algebra related with the invariance of the scalar equations of motion under conformal transformations. In particular, we associate infinite dimensional highest weight representations of the algebra sl(2,R) to quasinormal modes and frequencies of scalar fields in near extremal geometries and asymptotically Anti de Sitter geometries.
