On Fuzzy Ideals and Level Subsets of Ordered -Groupoids
Niovi Kehayopulu
We characterize the fuzzy left (resp. right) ideals, the fuzzy ideals and the fuzzy prime (resp. semiprime) ideals of an ordered -groupoid in terms of level subsets and we p…
How we pass from fuzzy -semigroups to fuzzy --semigroups
Niovi Kehayopulu
The results on fuzzy ordered semigroups (or on fuzzy semigroups) can be transferred to fuzzy ordered gamma (or to fuzzy gamma) semigroups. We show the way we pass from fuzzy ordere…
Comment on "Filtres in ordered -semigroups"
Niovi Kehayopulu
This is about the paper in the title by Kostaq Hila in Rocky Mt. J. Math. 41, no. 1 (2011), 189-203 for which corrections should be done.
Fuzzy semiprime subsets of ordered groupoids (groupoids)
Niovi Kehayopulu, Michael Tsingelis
A fuzzy subset of an ordered semigroup (or semigroup) is called fuzzy semiprime if for every (Definition 1). Following the terminology of semiprim…
On ordered -semigroups (-semigroups)
Niovi Kehayopulu
We add here some further characterizations to the characterizations of strongly regular ordered -semigroups already considered in Hacettepe J. Math. 42 (2013), 559--567. Our res…
