摘要: The response of a damped anharmonic oscillator, being model for many systems that undergo bifurcation, is determined in the presence small-amplitude parametric modulation arbitrary dynamics and statistics. Inertia always stabilizes trivial state suppresses growth bifurcating solution above shifted stability threshold. size both effects depends on spectrum. Explicit formulas threshold, solution, moments are given.
