摘要:

主要介绍了建立奇异摄动的扩散系统的随机平均化原理的直接平均方法和当前的进展,这种方法主要基于鞅问题和弱收敛.最后一部分也介绍了这种方法当前在奇异摄动的延迟和泛函系统的随机平均化原理中的进展和困难.

This paper mainly introduces the direct-averaging method for stochastic averaged principle of diffusion systems with singular perturbations,which is based on the martingale problem and the weak convergence.Finally,the advances and difficulties of this method in stochastic averaged principle of the diffusion delay and functional diffusion systems with singular perturbations.
