TITLE: Books about the spectra of non-compact Riemann surfaces
QUESTION [5 upvotes]: Hello,
Thanks for reading my question ! Could anybody give me some references ( books, papers containing elementary results etc ) on the eigen values and eigenspectra of NON-compact Riemann surfaces. I studied the compact cases briefly and want to know the analogues or further results for the non-compact ones.
Also, I need some references on probabilistic results on compact or non-compact Riemann surfaces, like random walks and Brownian motion on them etc.
Thank you !

REPLY [4 votes]: If your French is alright, Nicolas Bergeron has written a beautiful book, Le spectre des surfaces hyperboliques, available here, which covers many of these topics in detail.
