本文证明了半质环的一个交换性定理。
In this paper, the author proved the following commutativity theorem on semiprime rings:Let R be semiprime ning, if for any x, y∈R, there exist integers s=s(x)>1,t=t(x)>1(or s=s(y)>1,t=t(y)>1), such that(xy,xsyt)=0then R is commutative.The theorem improved some results appeared in reference -
