文摘Based on the well known fact that the quasinormal frequencies are the poles of the frequency domain Green’s function we describe a method that allows us to calculate exactly the quasinormal frequencies of the Klein-Gordon field moving in the three-dimensional rotating Bañados-Teitelboim-Zanelli black hole.

We think that the described procedure can be useful to calculate exactly the quasinormal frequencies of classical fields propagating in other backgrounds.
