本文主要研究两时间尺度耦合随机泛函微分方程。所考虑的系统有一个慢的部分和一个快的部分。这两个分量都依赖于慢分量的分段过程(无限维过程)。为了克服由于过去的依赖性和耦合的段过程的困难,这样的性质,如Hölder连续性和紧性的连续函数空间的研究首先为段过程。此外,还证明了固定x方程的解连续依赖于参数。然后利用鞅问题的形式,通过直接平均建立了一个平均原理。
This paper focuses on two-time-scale coupled stochastic functional differential equations (SFDEs). The system under consideration has a slow component and a fast component. Both components depend on the segment process (an infinite dimension process) of the slow component. To overcome the difficulty due to the past dependence and the coupling of the segment process, such properties as the Hölder continuity and tightness on a space of continuous functions are investigated first for the segment process. In addition, it is also shown that the solution of a fixed-xequation depends continuously on the parameters. Then using the martingale problem formulation, an average principle is established by a direct averaging.
