FUZZY K-IDEAL IN BCI-ALGEBRAS

The class of BCI-algebras which introduced by Iseki [7] is an important class of logical algebras which has two origins. One of the motivations for their use in based on set theory, the other o classical and non-classical propositional calculus. The concept of fuzzy sets introduced by Zadeh [8] was applied to BCIalgebra by Xi[3].Since then many researchers have investigated various properties of these algebras.Chun.et al.[2] constructed an extension of a k- semi ring and studied a k-ideal of a k-semi ring.
