„The book can be recommended both as a textbook and a review of the subject. The rich set of references allows one to catch up with the current literature. Exercises facilitate the study and will be of use to the lecturer. It can be a base of a solid graduate theoretical course in quantum chaos.“ (Pure and Applied Geophysics, 160, 2003)

„In summary, this is definitely an essential reference book for the specialist. It will also ably serve someone entering the field for the first time who needs to learn the theoretical state of the art in detail.“ (G. Summy (University of Oxford), Contemporary Physics 2002, vol. 43, page 232)
