摘要
设R是素环,对于环R上的一个可加映射g,如果有R上的导子go使得g(xy)=g(x)y+xgo(y),#x,y∈R,就说g是R上的广义导子.本文主要讨论素环上的广义导子,并相应地推广了素环上的导子情况。
Let R be prime ring.An additive mapping g:R→Ris called a generalized derivation of R if there exists a derivation g of R such thatg o (xy)=g(x)y+g (y),for all x,y ∈ R.In this note , we discuss the generalized derivation of prime ring, and generalize a number of results in the literature.
