The book "Aspects of Ergodic, Qualitative and Statistical Theory of Motion" is aimed at beginners in ergodic theory and is designed for both students and researchers in the field of mathematical physics. It provides a systematic treatment of characteristic problems in ergodic theory, employing a unified approach based on convergent power series and renormalization group methods. The fundamental concepts of ergodicity, such as Gibbs states, are developed in detail and applied to various systems, including Asonov systems and KAM theory. The book includes numerous examples to illustrate the concepts and offers a variety of interesting topics in the form of guided problems to deepen understanding.
