Non-autonomous Dynamical Systems,olution of amplitude and phase of the natural mode involved in the motion. The influence of damping, taken as auxiliary parameter, is also investigated. The region of the existence of the limit cycles are discussed, and their stability detected. Multivalued nonlinear responses, and consequent . are commented.locus-ceruleus 发表于 2025-3-27 10:33:17
