Abstract: In this paper, the notions of arity, Corn-union property (CUP), Join-hull commutativity (JHC) and weakly Join-hull commutativity (weakly JHC) are generalized to the fuzzy case. Also, it is proved that Corn-union property, Join-hull commutativity and weakly Join-hull commutativity L-convexities are of arity ≤2. Moreover, the CP and CC mappings between L-convexities with arity property are characterized.

Keywords: L-convexity, arity, join-hull commutativity, corn-union property, CP mapping, CC mapping
