    Sub-implicative ideals and sub-commutative ideals of BCI-algebras (English)
    0 references
    The authors introduce the notions of sub-implicative and sub-commutative ideals in BCI-algebras. These generalise the notion of \(p\)-ideals. They show that sub-implicative ideals are always sub-commutative. They characterize these types of ideals as well as positive implicative ideals. A major result is that an ideal is sub-implicative if and only if it is both positive implicative and sub-commutative.
