| Abstract | ||||
| Let R be a prime ring, extended centroid C , Utumi quotient ring U , and m, n ≥ 1 are fixed positive integers, F a generalized derivation associated with a nonzero derivation d of R . We study the case when one of the following holds: (i) F (x ) ◦m d(y ) = (x ◦ y ) n and (ii) (F (x ) ◦ d(y )) m = (x ◦ y ) n , for all x, y in some appropriate subset of R . We also examine the case where R is a semiprime ring. | ||||
