V. Cardoso et Jps. Lemos, Scaler, electromagnetic, and Weyl perturbations of BTZ black holes: Quasinormal modes - art. no. 124015, PHYS REV D, 6312(12), 2001, pp. 4015
We calculate the quasinormal modes and associated frequencies of the Banado
s-Teitelboim-Zanelli (BTZ) nonrotating black hole. This black hole Lives in
2+1 dimensions in an asymptotically anti-de Sitter spacetime. We obtain ex
act results for the wave function and quasinormal frequencies of scaler, el
ectromagnetic and Weyl (neutrino) perturbations.
