摘要:

利用环的广义多项式恒等式理论研究满足一定微分恒等式的环. 证明了: 设R是特征不为2的素环, L是R的非中心Lie理想, d是R上的导子,
如果对任意的u,v,w∈L, 有ul(d(v) ° v)mwn=0, 其中l,m,n是固定的正整数, 则d=0.

关键词: 素环, Lie理想, 导子

Abstract:

Using the theory of generalized polynomial identities, the author investigated the rings satisfying some differential identities. Let R be
a prime ring with the characteristic different from 2, L a noncentral Lie ideal of R and d a derivation of R, then d=0 if ul(d(v)°v)mwn=0 for all u,v,w∈L, where l,m,n are fixed positive integers.

Key words: prime ring, Lie ideal, derivation
