Some commutativity results for rings (Q5905592)

This paper gives several commutativity theorems for left \(s\)-unital, right \(s\)-unital, or \(s\)-unital rings satisfying polynomial identities of the form \([x^ ry+x^ n y^ m x^ s,x]=0\) or \([yx^ r+x^ n y^ m x^ s,x]=0\), where \(m\), \(n\), \(r\), and \(s\) are non-negative integers.
