On half-completion and bicompletion of quasi-metric spaces

Comment.Math.Univ.Carolinae 37,4 (1996) 749-756.

Abstract: We characterize the quasi-metric spaces which have a quasi-metric half- completion and deduce that each paracompact co-stable quasi-metric space having a quasi-metric half-completion is metrizable. We also characterize the quasi-metric spaces whose bicompletion is quasi-metric and it is shown that the bicompletion of each quasi-metric compatible with a quasi-metrizable spaceX is quasi-metric if and only ifX is finite.

Keywords: quasi-metric, quasi-uniform, half-completion, bicompletion, uniformly weakly regular
