Özet
Let R be a prime ring of characteristic different from 2, C its extended centroid and L a non-central Lie ideal of R. If F:R→R and G:R→R are two non-zero generalized derivations of R such that [F(u),G(u)]=0 for all u∈L, then G=λF for some λ∈C except possibly when R satisfies the standard identity s4 of degree 4.
