摘要 设A,B是有单位元的结合环,M是一个非零(A,B)-双模,D为形式三角矩阵环Tri(A,M,B)={(a0mb)|a∈A,m∈M,b∈B}上的导子。如果对于任意X,Y∈Tri(A,M,B),D(Xm)=(D(X))n或D((XY)n)=D(Xn)D(Yn)成立,其中m,n≥1为固定的整数,那么D=0。 Let A,B be commutative rings with identity,Ma nonzero( A,B)-bimodule and D be a derivation of formal triangular matrix ring Tri(A,M,B)={(a0mb)|a∈A,m∈M,b∈B}.If D( Xm) =( D( X))nor D(( XY)n) = D( Xn) D( Yn) for all X,Y∈Tri( A,M,B),where m,n≥1 are fixed integers,then D = 0.
