Commutative Intersection-Soft Ideals in BCK-Algebras
Young Bae Jun

In BCK-algebras, the notion of commutative intersection-soft ideal is introduced, and related properties are investigated. Characterizations of a commutative intersection-soft ideal are considered. Conditions for an intersection-soft ideal to be commutative are provided. Extension property of a commutative intersection-soft ideal is established. The problem of classifying (commutative) intersection-soft ideals by their inclusive sets is solved.
