  • Abstract: 利用路径积分法研究一类非线性动力系统的混沌响应,计算 lévy 噪声 激励的混沌系统的瞬时概率密度等概率性质,并讨论 lévy 噪声对确定性系统混 沌运动的影响。研究表明,在噪声强度一定的情况下,其随机系统的概率密度 的演化可以用来刻画该混沌吸引算子的结构特征。
  • Path integration method was used to study the chaotic response of the nonlinear dynamical systems and the probabilistic nature such as the instantaneous probability density of chaotic systems with the lévy noise was calculated. Then the impacts of lévy noise on chaotic movement of the deterministic systems were discussed. The findings show that evolution of probability density of chaotic systems can be used to character structure feature of such chaotic attractor.
