摘要: Abstract The Brownian motion of the Duffing oscillator is analyzed in case when damping small compared with its frequency, whereas nonlinearity may be arbitrary. expressions for time-correlation functions coordinates are obtained an explicit form. If small, dynamics system shown to determined by a relation between frequency straggling due fluctuations amplitude and damping. At large correlators do not depend on dependences spectral representations investigated various ratios parameters.
