Gibbs过程的不一致耦合及其在Poisson逼近中的应用

Disagreement coupling of Gibbs processes with an application to Poisson approximation

Günter Last, Moritz Otto

摘要:

我们讨论了一个细化和嵌入过程,以构建有限的吉布斯过程与给定的Papangelou强度。扩展Hofer-Temmel(2019)和Hofer-Temmel和Houdebert(2019)中的方法,我们将使用它来耦合两个具有不同边界条件的有限Gibbs过程。作为一个应用,我们将建立泊松近似的点过程从某些无限体积吉布斯过程通过相关细化。作为另一个应用,我们将讨论某些吉布斯过程的空空间概率。

英文摘要:

We discuss a thinning and an embedding procedure to construct finite Gibbs processes with a given Papangelou intensity. Extending the approach in Hofer-Temmel (2019) and Hofer-Temmel and Houdebert (2019) we will use this to couple two finite Gibbs processes with different boundary conditions. As one application we will establish Poisson approximation of point processes derived from certain infinite volume Gibbs processes via dependent thinning. As another application we shall discuss empty space probabilities of certain Gibbs processes.
