In this post, we will see the book Applied Methods in The Theory of Nonlinear Oscillations by V. M. Starzhinskii.
The book is aimed at engineers with a strong mathematical background, scientists working in mechanics and applied mathematics, and undergraduate and postgraduate students of Applied Physics and Physics and Mathematics departments. The book is based on a course of lectures presented by the author
to engineering students at the Mechanics and Mathematics Department
of Moscow University in 19561976.
The book has two parts
Part One of the book is devoted to the combination of the Lyapunov, Poincare, and averaging methods as applied to the analysis of oscillations in Lyapunov and nearly Lyapunov systems.
The second part of the book is also based on the results achieved in one of the classical methods developed in the years spanning the late 19th and early 20th centuries, the theory of normal forms (Poincare, Lyapunov, Dulac, Siegel, Moser, Arnold, Pliss, and others).
The book was translated from the Russian by V. I. Kisin and was first published by Mir Publishers in 1980.
