摘要
Abstract
Let R be a prime ring with charR≠2, U(∈)Z(R) a Lie ideal such that u2∈U for all u∈U, and δ a generalized derivation associated with d.If either δ(U)(∈)Z(R) or[δ(x),δ(y)=x,y] with d(Z(U))≠0 for all x, y∈U, then there exists q∈Qr(Rc) such that δ(x)=qx for all x∈R. Further, if a∈R and [a,δ(x)]∈Z(R) with d(Z(U))≠0 for all x∈U, then a∈Z(R).关键词
