High-Order Variational Calculation for the Frequency of Time-Periodic Solutions
arXiv:math-ph/0208032 · doi:10.1103/PhysRevE.67.016604
Abstract
We develop a convergent variational perturbation theory for the frequency of time-periodic solutions of nonlinear dynamical systems. The power of the theory is illustrated by applying it to the Duffing oscillator.
