**Positive implicative ideals of BCK-algebras based on intersectional soft sets.**
*(English)*
Zbl 1266.06028

Summary: The aim of this paper is to lay a foundation for providing a soft algebraic tool in considering many problems that contain uncertainties. In order to provide these soft algebraic structures, the notion of int-soft positive implicative ideals is introduced, and related properties are investigated. Relations between an int-soft ideal and an int-soft positive implicative ideal are established. Characterizations of an int-soft positive implicative ideal are obtained. An extension property for an int-soft positive implicative ideal is constructed. The \(\wedge\)-product and \(\vee\)-product of int-soft positive implicative ideals are considered, and the soft intersection (resp., union) of int-soft positive implicative ideals is discussed.
