Commutativity of rings with derivations

Acta Mathematica Hungarica, 2010
The authors extend a theorem of \textit{H. E. Bell} and \textit{M. N. Daif} [Acta Math. Hung. 66, No. 4, 337-343 (1995; Zbl 0822.16033)] proving that the commutativity of a unital prime ring with a non-zero derivation is equivalent to several conditions on derivations of some powers (Theorem 2.2). Under the additional assumption that the identity is in
