摘要: 利用GPI素环的结构性质以及域上向量空间与其自同态环的关系证明了: 具有特殊形式的两个广义导子的复合可以在素环的非零左理想上起广义导子作用, 并对这几种特殊形式的广义导子给出了完整的描述, 从而给出了广义导子的复合在素环的非零左理想上起广义导子作用的充分必要条件.

Abstract: Using structure properties of prime rings satisfying GPI and the relation of vector spaces and their endmorphism rings, we showed that it is posible that the composition of two generalized derivations with special forms may act like generalized derivation on the left ideals of prime rings. And we got an equivalent condition for generalized derivations to have this property.

Key words: prime ring, generalized derivation, composition
