有限维向量空间上概率测度的中心问题

Centering problems for probability measures on finite dimensional vector spaces

Andrzej Łuczak

摘要:

本文讨论了有限维向量空间上概率测度的各种中心化问题。我们证明了对于每一个这样的测度,对于$μ$的每一个对称性$S$,都存在一个满足$μ*δ(h)=S(μ*δ(h))$的向量$h$,从而推广了Jurek关于全测度的结果.对于无限可分的$μ$,给出了$h$的显式形式.主要结果的文件包括在分析准分解(运营商半稳定和运营商稳定)措施和寻找条件存在一个“普遍中心”这样的措施,以严格准分解。

英文摘要:

The paper deals with various centering problems for probability measures on finite dimensional vector spaces. We show that for every such measure there exists a vector $h$ satisfying $μ*δ(h)=S(μ*δ(h))$ for each symmetry $S$ of $μ$, generalizing thus Jurek's result obtained for full measures. An explicit form of the $h$ is given for infinitely divisible $μ$. The main result of the paper consists in the analysis of quasi-decomposable (operator-semistable and operator-stable) measures and finding conditions for the existence of a `universal centering' of such a measure to a strictly quasi-decomposable one.
