ABSTRACT: Fuzzy
greedoids were recently introduced as a fuzzy set generalization of (crisp)
greedoids. We characterize fuzzy languages which define fuzzy greedoids, give
necessary properties and sufficient properties of the fuzzy rank function of a
fuzzy greedoid, give a characterization of the rank function for a weighted
greedoid, and discuss the rank closure of a fuzzy greedoid.
