Abstract :
In this paper, we define the notions of ultra and involution ideals in BCK-algebras. Then we get the relation among them and other ideals as (positive) implicative, associative, commutative and prime ideals. Specially, we show that in a bounded implicative BCK-algebra, any involution ideal is a positive implicative ideal and in a bounded positive implicative lower BCK-semilattice, the notions of prime ideals and ultra ideals are coincide.
