TITLE: Book about ergodic theory, group actions and number theory
QUESTION [5 upvotes]: Does anyone know about an introductory book showing the intersection between ergodic theory, group actions and number theory? I have been looking for but it has been impossible to me.

REPLY [3 votes]: I like the survey article "Interactions Between Ergodic Theory, Lie Groups, and. Number Theory" by Marina Ratner. Look it up in Google.
