N-centralizing generalized derivations on left ideals *

2012
Let R be a prime ring with center Z(R), right Utumi quotient ring U and extended centroid C, S be a non-empty subset of R and n ≥ 1 a fixed integer. A mapping f : R → R is said to be n-centralizing on S if [f(x), xn] ε Z(R), for all x ε S. In this paper we will prove that if F is a non-zero generalized derivation of R, I a non-zero left ideal of R, n ≥
