SUPER UNIFORM SPACES

Abstract A new, generalized form, of uniformity, the so called super uniformity is defined and studied. It is based on the concept of fuzzy filter, as introduced by Eklund and Gaaler [EG]. To each super uniformity, a fuzzy α-uniformities system can be associated. They will be called α-levels. These α-levels are fuzzy uniformities in the sense of Lowen, for α=1, and α-modifications with pleasant properties, for α≠1. The *-version of super uniformities is related, at level 1, with T-uniformities, as defined by Hohle [Ho]. A criterion for a given family of prefilters {F α}αeI0 on a set X to generate a fuzzy filter 𝔉 on X with {F α)αe I0 as its family of α-level prefilters, that is 𝔉α = F α is found, and extended to super uniformities. Finally, super uniformities are related with fuzzy topologies in the sense of Sostak.
