Simultaneous extensions of metrics and ultrametrics of high power

In this paper, generalized metrics mean taking values in general linearly ordered Abelian groups. Using the Hahn fields, we first prove that for every metric space, if set of Archimedean equivalence classes range group has an infinite decreasing sequence, then non-empty closed subset space is a uniform retract ambient space. Next construct simultaneous extensions and ultrametrics. From existence extensors metrics, characterize final compactness metrizable spaces using completeness metrics.
