%! A COMMUTATIVITY CONDITION FOR RINGS
%R
%X In this paper, we use the structure theory to prove an analog to a well-known
theorem of Herstein as follows: Let R be a ring with center C such that for all x,y ?
R either [x,y]= 0 or x-x [x,y]? C for some non negative integer n= n(x,y) dependingon x and y. Then R is commutative.
