分级碎片化

Ranked Fragmentations

Julien Berestycki

摘要:

在本文中,我们定义和研究自相似的排名碎片。我们首先表明,任何排名的碎片是一些分区值的碎片的图像,事实上有一个一一对应的法律,这两种类型的碎片。然后,我们给出了一个明确的建设齐次排名破碎的泊松点过程。最后,我们使用这种结构和经典的结果记录的泊松点过程研究的小时间行为的排名碎片。

英文摘要:

In this paper we define and study self-similar ranked fragmentations. We first show that any ranked fragmentation is the image of some partition-valued fragmentation, and that there is in fact a one-to-one correspondence between the laws of these two types of fragmentations. We then give an explicit construction of homogeneous ranked fragmentations in terms of Poisson point processes. Finally we use this construction and classical results on records of Poisson point processes to study the small-time behavior of a ranked fragmentation.
