Abstract

In this paper we study some sufficient conditions for commutativity of a ring according to Jacobsons'idea. Jacobson proved that if R isaringsatisfying xn =x (n>1) foreach x∈R, then R is commutative. In this paper, we show that R is commutative if for every x, y ∈ R there exists a positive integer n = n(x, y) such that (x[x,y])n =x[x,y].
