An isometric extensor of metrics
Yoshito Ishiki
In this paper, for a metrizable space , we consider the space of metrics that generate the same topology of , and that space of metrics is equipped with the supremum metrics.…

Constructions of Urysohn universal ultrametric spaces
Yoshito Ishiki
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 func…

Simultaneous extensions of metrics and ultrametrics of high power
Yoshito Ishiki
In this paper, generalized metrics mean metrics taking values in general linearly ordered Abelian groups. Using the Hahn fields, we first prove that for every generalized metric sp…
