چکیده مقاله
In this paper we introduce a new de tion for center of a polygroup in a di erent way Also, we de ne nilpotent polygroup and upper central series of a polygroup We show that each normal subpolygroup and every qoutient of a polygroup is nilpotent too Moreover, we prove that each minimal normal subpolygroup of a nilpotent polygroup is contained in the center of it
