Regular and Chaotic Oscillations

Mechanics-oriented monograph from one of the leading Russian physicists. Most of the established books in this field (Nayfeh, Minorski) are out of date and do not regard the tremendous developments of nonlinear dynamics in the past 20 years.

Presented in a non-traditional manner with emphasis on the new result in the theory obtained partially by the author, who is one of the leading experts in the area Includes modern topics such as synchronization and chaotization of self-oscillatory systems and the influence of weak random vibration Includes supplementary material: sn.pub/extras

Klappentext
In the present book the modern theory of non-linear oscilla- tions both regular and chaotic, is set out, primarily, as applied to mechanical problems. The material is presented in a non-traditional manner with emphasizing of the new results of the theory otained partially by the author, who is one of the leading experts in the area. Among the up-to-date topics are synchronization and chaotization of self-oscillatory sy- stems, the influence of weak random vibration on modificati- on of characteristics and behavior of the non-linear systems etc. One of the purposes of the book is to convince the rea- ders of the necessity of a thorough study of this theory and to show that it can be very useful in engineering investiga- tions. The primary readers for this book are researchers working with different oscillatory processes, and both un- der-graduate and post-graduate students interested in a deep study of the general laws and applications of the theory of nonlinear oscillations. The instructors can find here new materials for lecturess and optinal courses.
