摘要 设R是素环,L是R上非中心化的Lie理想,若d和g是R上的导子,使得对任意的u∈L,(d(u)u-ug(u))2都属于R的中心,则d=g=0或R满足4个变量的标准恒等式s4. Let R be a prime ring with L a noncentral Lie ideal of R. If d and g are the derivations of R such that ( d(u) u - ug (u) )^ 2 is central for all u E L , then d = g = 0 or R satisfies s4 the standard identity in 4 variables.
