Basic Ergodic Theory (3/E)

M.G. Nadkarni

This is an introductory text on ergodic theory. The presentation has a slow pace and the book can be read by any person with a background in basic measure theory and metric topology. A new feature of the book is that the basic topics of ergodic theory such as the PoincarÃ© recurrence lemma, induced automorphisms and Kakutani towers, compressibility and E. Hopf's theorem, the theorem of Ambrose on representation of flows, are treated at the descriptive set -theoretic level before their measure -theoretic or topological versions are presented. In addition, topics centering around the Glimm-Effros theorem, which have so far not found a place in texts on ergodic theory are discussed in this book.

The third edition has, among other improvements, a new chapter on Additional Topics that include Liouville's theorem of classical mechanics, basics of Shannon Entropy and the Kolmogorov-Sinai theorem, and van der Waerden's theorem on arithmetical progressions.
