Consider now the infinite hyper BCK-algebra (H, ◦, 0) given also by Harizavi in [3], where H = {0, 1, 2, . . .} ∪ { 1n : n = 2, 3, ...} and “ ◦ ” is defined as follows: x ◦ y = { {0, x} if x ≤ y {x} if x > y for all x, y ∈ H. For convenience, let N = {1, 2, ...}, N0 = N ∪ {0}, and let Jk = { 1 m : m is a positive integer and m ≥ k}.	cache/ejpam-3632.pdf	txt/ejpam-3632.txt
