Can anyone suggest me some books or papers that include details about spectral theory on Hyperbolic spaces or related topics such as scattering theory on Hyperbolic spaces?
After some googling, I can only find papers by Jean-Philippe Anker and Vittoria Pierfelice about Schrodinger equations on Hyperbolic spaces, see e.g. http://arxiv.org/abs/0801.3523. I hope to find some references that contain more basic theory on Hyperbolic space, such as the spectral theory of Laplacian on $\mathbb{H}^n$ . Thanks in advance.
