Method for Constructing Periodic Solutions of Nonlinear Differential Equations
Abstract
We justify an analytical method for constructing periodic solutions of nonlinear systems of
ordinary differential equations of polynomial type. Periodic solutions are constructed in the form
of Fourier series in which the coefficients are polynomials depending on a parameter, which is not
assumed to be small. Two examples are considered: the van der Pol equation and the Lorenz
system.
