摘要: 设G=G(A,M,N,B)是一个广义矩阵代数, a:G→G是一个映射(无可加性假设). 利用代数分解的方法, 证明: 如果对任意的X,Y∈G, 且X和Y至少有一个是幂等元时, a(XY)=a(X)Y+Xa(Y)成立, 则a是G上的可加导子.

Abstract: Let G=G(A,M,N,B) be a generalized matrix algebra, and a:G→G be a map (without the assumption of additivity). Using the  method of algebraic decomposition, we proved that if  a(XY)=a(X)Y+Xa(Y) held for any X,Y∈G and  at least one of X  and Y was idempotent, then a was an additive derivation on G.

Key words: local derivable map, derivation, generalized matrix algebra
