度量空间中的Lipschitz聚类

Lipschitz clustering in metric spaces

Leonid V. Kovalev

摘要:

本文讨论了度量空间的Lipschitz聚簇性,即在有限子集空间之间Lipschitz收缩的存在性。这个属性的障碍可以是空间的拓扑或几何特征。证明了一致不连通空间具有Lipschitz聚类性质,而对于某些连通空间,缺乏足够短的连通曲线是一个障碍.证明了这一性质在拟齐次映射下是不变的,但在拟对称映射下不是不变的。

英文摘要:

In this paper, the Lipschitz clustering property of a metric space refers to the existence of Lipschitz retractions between its finite subset spaces. Obstructions to this property can be either topological or geometric features of the space. We prove that uniformly disconnected spaces have the Lipschitz clustering property, while for some connected spaces, the lack of sufficiently short connecting curves turns out to be an obstruction. This property is shown to be invariant under quasihomogeneous maps, but not under quasisymmetric ones.
