On the universal ultrametric space

Ukrainian Mathematical Journal, 1994
Summary: An ultrametric space in which any separable ultrametric space is isometrically imbedded is constructed. We show how, by using this universal space, any separable ultrametric space can be imbedded into \(l_1\), \(l_2\) and \(c_0\).

Constructions of Urysohn Universal Ultrametric Spaces [PDF]

P-Adic Numbers, Ultrametric Analysis, and Applications, 2023
In this paper, we give new constructions of Urysohn universal ultrametric spaces. We first characterize a Urysohn universal ultrametric subspace of the space of all continuous functions whose images contain the zero, from a zero-dimensional compact Hausdorff space without isolated points into the space of non-negative real numbers equipped with the ...

Wavelets on ultrametric spaces [PDF]

Applied and Computational Harmonic Analysis, 2005
The authors consider ultrametric spaces with a metric \(| xy| \) satisfying the strong triangle inequality \(| ab| \leq\max(| ac| ,| cd| )\) for all \(c\). They construct measures in ultrametric spaces and introduce bases in quadratically integrable (complex valued) function spaces.

Polish ultrametric Urysohn spaces and their isometry groups [PDF]

Topology and Its Applications, 2011
