TY - JOUR JF - IJMSI JO - IJMSI VL - 9 IS - 1 PY - 2014 Y1 - 2014/5/01 TI - On Hyper Pseudo BCK-algebras TT - N2 - In this paper, we introduce the notion of hyper pseudo B C K - algebras, which is a generalization of pseudo BCK -algebras and hyper BCK -algebras and we investigates some related properties. In follow, we de ne some kinds of hyper pseudo BCK -ideals of a hyper pseudo BCK - algebra and we find the relations among them. Finally, we characterize the hyper pseudo BCK -ideals of type 4 generated by a nonempty subset. SP - 13 EP - 29 AU - Borzooei, R. A. AU - Rezazadeh, A. AU - Ameri, R.
