摘要
设A是一个含单位元I的半素的复范数*-代数,我们证明了若δ是A到其自身的连续的线性映射,且对任意的∈P,都有δ(p^2)=δ(P)p+pδ(p)-pδ(I)p对于任意的投影p∈A,和D_A在H_A中是稠密的,则δ是广义Jordan导子,并且因此是广义导子.
In this note, assume that A is a prove that a continuous linear mapping δ from A semiprime normed complex^* - algebra with identity, we into itself satisfied δ (p^2) = δ(p)p + pδ(p) - pδ(I)p for all projection p in A, and DA is dense in HA, then δ is a generalized Jordan derivation, and therefore is a generalized derivation.
