We view ultrametric spaces as two-sorted structures consisting of a set of points and of a linearly ordered set of distances. We call the appropriate notion of embeddings distance-…

On the connectivity of graph Lipscomb's space
W. Kubiś, R. Miculescu, A. Mihail +1
A central role in topological dimension theory is played by Lipscomb's space since it is a universal space for metric spaces of weight . On the one han…
