摘要 设A是一个作用在Banach空间X上的含单位元I的标准算子代数,φ:A→B(X)是一个可加映射。证明了如果存在正整数m,n,r,使得(m+n)φ(Ar+1)-(mφ(A)Ar+nArφ(A))∈F I对任意的A∈A成立,那么存在λ∈F,使得对任意的A∈A,φ(A)=λA。 Let A be a a standard operator algebra on Banach space C with unit I,andφ:A→B(X)is an additive mapping.In this paper,we prove that if there is some positive integer number m,n,r satisfies(m+n)φ(Ar+1)-(mφ(A)Ar+nArφ(A))∈fI,for all A∈A,then there exists someλ∈f such thatφ(A)=)tA for all∈A.
