TLDR
The isometry group Iso (U ) of the universal Urysohn metric space U equipped with the natural Polish topology is a Levy group in the sense of Gromov and Milman, that is, admits an approximating chain of compact subgroups as discussed by the authors.

On subgroups of minimal topological groups

TL;DR: A topological group is a subgroup of a minimal topologically simple Roelcke-precompact group of the form Iso (M ), where M is an appropriate non-separable version of the Urysohn space as discussed by the authors.

TL;DR: In 2003, Kechris, Pestov and Todorcevic showed that the structure of certain separable metric spaces is closely related to the combinatorial behavior of the class of their finite metric spaces.

Metric Structures for Riemannian and Non-Riemannian Spaces

TL;DR: In this paper, Loewner proposed a metric structure with a bounded Ricci Curvature for length structures on families of metric spaces, where the degree and dilatation of the length structure is a function of degree and degree.

Asymptotic theory of finite dimensional normed spaces

TL;DR: The concentration of measure phenomenons in the theory of Normed spaces was discussed in this paper, where the Rademacher projection was applied to the case of finite Dimensional Normed Spaces.
