On the modular metric topology

Olivier Olela-Otafudu ⟨olivier.olela-otafudu@ul.ac.za⟩

Abstract:

Following earlier authors in this subject, the topology induced by a modular metric is herein called a modular topology. We show that such a topology is metrizable. More precisely, we show that the uniform topology induced by the uniformity on the modular set of a modular pseudometric is metrizable. In addition, we observe that such a topology is coarser than the underlying topology of the uniformity induced by the corresponding pseudometric. Other related immediate observations are also presented. \begin{references}{99}
