Abstract
A J-ring is a ring R with the property that for every x in R there exists an integer
n(x)>1 such that xx xn
=)(
, and a well-known theorem of Jacobson states that a J-
ring is necessarily commutative. With this as motivation, we define a generalized J-
ring to be a ring R with the property that for all x, y in R0 there exists integers
1)(,1)( >=>= ymmxnn such that mn
xyyx - is nilpotent, where R0 is a certain
subset of R. The commutativity behavior of such rings is considered.
