![]() ![]() Topological pressure and equilibrium states are discussed, and a proof is given of the variational principle that relates pressure to measure-theoretic entropies. Topological entropy is introduced and related to measure-theoretic entropy. The family of invariant probability measures for such a transformation is studied and related to properties of the transformation such as topological traitivity, minimality, the size of the non-wandering set, and existence of periodic points. The second part of the text focuses on the ergodic theory of continuous transformations of compact metrizable spaces. Some examples are described and are studied in detail when new properties are presented. The first part of the text is concerned with measure-preserving transformations of probability spaces recurrence properties, mixing properties, the Birkhoff ergodic theorem, isomorphism and spectral isomorphism, and entropy theory are discussed. It is hoped the reader will be ready to tackle research papers after reading the book. The mathematical prerequisites are summarized in Chapter 0. ![]() Abstract: This text provides an introduction to ergodic theory suitable for readers knowing basic measure theory.
