多型超过程的主干分解

Backbone decomposition of multitype superprocesses

Dorottya Fekete, Sandra Palau, Juan Carlos Pardo, José Luis Pérez

摘要:

在本文中,我们提供了一个所谓的多类型超临界超过程的骨架分解的结构。虽然骨干分解是相当有名的连续状态分支过程和超过程在一个类型的情况下,到目前为止,没有这样的分解,甚至描述多产的系谱已经给出了多类型的情况下。在这里,我们专注于超过程,但通过关闭运动,我们得到了多类型连续状态分支过程的多产主干分解,作为我们结果的一个简单结果。

英文摘要:

In this paper, we provide a construction of the so-called backbone decomposition for multitype supercritical superprocesses. While backbone decompositions are fairly well-known for both continuous-state branching processes and superprocesses in the one-type case, so far no such decompositions or even description of prolific genealogies have been given for the multitype cases. Here we focus on superprocesses, but by turning the movement off, we get the prolific backbone decomposition for multitype continuous-state branching processes as an easy consequence of our results.
