Some properties of semi-continuous functions and quasi-uniform spaces.
A Sequentially Compact Non-compact Quasi-pseudometric Space.
Quasi-metrization and completion for Pervin's quasi-uniformity.
R. Stoltenberg characterized in [2] those quasi-uniformities which are quasi-pseudometrizable, as well as those quasi-metric spaces which have a quasi-metric completion. In this paper we follow Stoltenberg's work by giving characterizations for quasi-metrizability and quasi-metric completion for a particular type of quasi-uniform spaces, the Pervin's quasi-uniform space.
