壁面有收缩孔的洛伦兹过程
Lorentz Process with shrinking holes in a wall
摘要:
我们确定了扩散尺度限制的周期性洛仑兹过程在一个带几乎反射壁的起源。在这里,几乎反射意味着墙壁包含一个随着时间而变小的小孔。极限过程是一个拟反射布朗运动,它是马尔可夫的,但不是强马尔可夫的。本地时间的周期性洛伦兹过程的结果,具有独立的利益,也被发现和使用。
英文摘要:
We ascertain the diffusively scaled limit of a periodic Lorentz process in a strip with an almost reflecting wall at the origin. Here, almost reflecting means that the wall contains a small hole waning in time. The limiting process is a quasi-reflected Brownian motion, which is Markovian but not strong Markovian. Local time results for the periodic Lorentz process, having independent interest, are also found and used.
