Va. Dvinskikh et Sv. Frolov, Estimation of the parameters of the spectral components of second-order nonlinear systems, TECH PHYS L, 26(2), 2000, pp. 173-174
A nonlinear conservative Lyapunov system is analyzed, and satisfactory agre
ement between the analytical solution and the results of numerical analysis
is obtained. Oscillation spectra of a nonautonomous nonlinear system that
is close to the Lyapunov one are discussed. (C) 2000 MAIK "Nauka/Interperio
