Unrestricted Harmonic Balance

Zeitschrift für Naturforschung A, 1983
Abstract The method of Unrestricted Harmonie Balance (UHB) is a generally applicable procedure to determine the Fourier coefficients and constants of motion (frequency, velocity) of non-linear periodic phenomena in time and space and was outlined and applied to various problems in chemistry in preceding papers. Here the truncation error
