Quasi a-ideals in BCI-algebras

Non-classical logic has become a considerable formal tool for computer science on computational intelligence to deal with fuzzy information and uncertain information. BCI-algebras and BCK-algebras are two classes of non-classical logic algebras that are introduced by Iseki in 1966 and they are algebraic formulations of BCK and BCI-system in logic algebras. Lele used the notion of fuzzy point to study some properties of BCI-algebras. Jun and Lele used the notion of fuzzy points for establishing quasi q-ideal in the set of all fuzzy points of a fixed BCI-algebras and give some characterizations of these ideals.
