摘要翻译：
回顾最近关于将基于阈值的抽样描述为准等距映射的结果，导出了事件序列空间的度量和拓扑结构的数学含义。在此背景下，将事件序列空间推广到具有Hermann Weyl差异测度的赋范空间。用Jordan分解性质刻画了有限差分范数序列。它的对偶范数原来是总变差的范数。作为副产品，得到了序列缺乏单调性的一个测度。进一步的结果是差异范数与总变差之间的一个不等式，类似于海森堡的测不准关系。

英文摘要：
Recalling recent results on the characterization of threshold-based sampling as quasi-isometric mapping, mathematical implications on the metric and topological structure of the space of event sequences are derived. In this context, the space of event sequences is extended to a normed space equipped with Hermann Weyl's discrepancy measure. Sequences of finite discrepancy norm are characterized by a Jordan decomposition property. Its dual norm turns out to be the norm of total variation. As a by-product a measure for the lack of monotonicity of sequences is obtained. A further result refers to an inequality between the discrepancy norm and total variation which resembles Heisenberg's uncertainty relation.
