Ergodic Theory via Joinings
Share this pageEli Glasner
This book introduces modern ergodic theory. It emphasizes a new approach that
relies on the technique of joining two (or more) dynamical systems. This
approach has proved to be fruitful in many recent works, and this is the first
time that the entire theory is presented from a joining perspective.
Another new feature of the book is the presentation of basic definitions of
ergodic theory in terms of the Koopman unitary representation associated with a
dynamical system and the invariant mean on matrix coefficients, which exists
for any acting groups, amenable or not. Accordingly, the first part of the book
treats the ergodic theory for an action of an arbitrary countable group.
The second part, which deals with entropy theory, is confined (for the sake
of simplicity) to the classical case of a single measure-preserving
transformation on a Lebesgue probability space.
Topics treated in the book include:
- The interface between topological dynamics and ergodic theory;
- The theory of distal systems due to H. Furstenberg and R. Zimmer—presented for the first time in monograph form;
- B. Host's solution of Rohlin's question on the mixing of all orders for systems with singular spectral type;
- The theory of simple systems;
- A dynamical characterization of Kazhdan groups;
- Weiss's relative version of the Jewett-Krieger theorem;
- Ornstein's isomorphism theorem;
- A local variational principle and its applications to the theory of entropy pairs.
The book is intended for graduate students who have a good command of basic measure theory and functional analysis and who would like to master the subject. It contains many detailed examples and many exercises, usually with indications of solutions. It can serve equally well as a textbook for graduate courses, for independent study, supplementary reading, or as a streamlined introduction for non-specialists who wish to learn about modern aspects of ergodic theory.

Reviews & Endorsements
The first book which presents the foundations of ergodic theory in such generality contains a selection of more specialized topics so far only available in research papers. It also includes a good dose of abstract topological dynamics … a very valuable source of information … the writing is very clear and precise … There is an excellent, wide-ranging bibliography … among books on abstract measure-theoretic ergodic theory, Glasner's is the most ambitious in scope … there are many topics which are available here for the first time in a book. This is a very impressive achievement which I look forward to returning to often.
