Abstract | ||||
Let R be a 2-torsion-free prime ring with center Z(R), F a generalized derivation associated with a nonzero derivation d, L a Lie ideal of R. If ðdðuÞl1FðuÞl2dðuÞl3FðuÞl4 . . . FðuÞlk Þn ¼ 0 for all u 2 L, where l1, l2, . . . , lk are fixed non-negative integers not all zero, and n is fixed positive integer, then L ˝ Z(R). We also examine the case when R is a semiprime ring. Finally, we apply the above result to Banach algebras. | ||||
