随机组合结构中的再生

Regeneration in Random Combinatorial Structures

Alexander V. Gnedin

摘要:

金曼的划分结构理论有两个顶点:一般的颜料盒表示法,通过自然抽样程序将有限划分与假设的无穷总体联系起来,称为金曼的颜料盒;该理论的中心例子--Ewens-Pitman双参数划分族。在这些笔记中,我们进一步发展理论,通过传递到结构丰富的顺序收集的类别;扩展类的听话的模型,探索再生的想法;分析再生性能的Ewens-Pitman分区;研究渐近特征的再生成分。

英文摘要:

Theory of Kingman's partition structures has two culminating points: the general paintbox representation, relating finite partitions to hypothetical infinite populations via a natural sampling procedure, known as Kingman's paintbox; a central example of the theory - the Ewens-Pitman two-parameter family of partitions. In these notes we further develop the theory by passing to structures enriched by the order on the collection of categories; extending the class of tractable models by exploring the idea of regeneration; analysing regenerative properties of the Ewens-Pitman partitions; studying asymptotic features of the regenerative compositions.
