考虑具有首次积分的动力系统的快速振荡随机扰动。证明了如果动力系统在第一积分为常数的相空间子集中是遍历的,则第一积分在适当时间尺度上的演化可用扩散过程描述.
We consider fast oscillating random perturbations of dynamical systems with first integrals. We prove that if the dynamical system is ergodic in the subset of the phase space where the first integrals are constants, then the evolution of the first integrals in a proper time scale is described by a diffusion process.
