Elements of the Mathematical Theory of Multi-Frequency Oscillations (1991)Hardcover - 1991, 31 October 1991

Translated from the original Russian edition of 1987 (Nauka, Moscow), this volume deals with the theory of multi-frequency oscillations as a motion of a dynamical system which describes a recurrent trajectory on an invariant toroidal manifold of the system. In this way, the invariant toroidal manifo
