Abstract
Let n be a fixed positive integer, R be a prime ring, D and G two derivations of R and L a noncentral Lie ideal of R. Suppose that there exists 0 ≠ a ∈ R such that a(D(u)u n−u n G(u)) = 0 for all u ∈ L, where n ≥ 1 is a fixed integer. Then one of the following holds:
-
1.
D = G = 0, unless R satisfies s 4;
-
2.
char (R) ≠ 2, R satisfies s 4, n is even and D = G;
-
3.
char (R) ≠ 2, R satisfies s 4, n is odd and D and G are two inner derivations induced by b, c respectively such that b + c ∈ C;
-
4.
char (R) = 2 and R satisfies s 4.
We also investigate the case when R is a semiprime ring.
