Abstract

We show that the definition of a fuzzy set is directly related to the existence of a weightable quasi-metric on a universe. This relationship

is also explored in terms of functional equations coming either from the membership function of a fuzzy set or from the disymmetry function of

a quasi-metric.

Keywords

Fuzzy sets, weightable quasi-metrics, functional equations, representable total preorders
