Haar空集与Haar微薄集:综述与新结果

Haar null and Haar meager sets: a survey and new results

Márton Elekes, Donát Nagy

摘要:

我们调查结果Haar空子集(不一定是局部紧)波兰集团。本文的目的是收集各种可能的定义的Haar空集的基本属性,并审查的技术,可以使读者证明在这方面的结果。我们还提出了几个最近推出的想法,包括哈尔微薄集,这是非常类似的哈尔空集的概念。我们证明了一些结果在一个更一般的设置比他们原来证明的文件,并证明了一些结果Haar微薄集已经知道Haar空集。

英文摘要:

We survey results about Haar null subsets of (not necessarily locally compact) Polish groups. The aim of this paper is to collect the fundamental properties of the various possible definitions of Haar null sets, and also to review the techniques that may enable the reader to prove results in this area. We also present several recently introduced ideas, including the notion of Haar meager sets, which are closely analogous to Haar null sets. We prove some results in a more general setting than that of the papers where they were originally proved and prove some results for Haar meager sets which were already known for Haar null sets.
