摘    要:设B( X)是无限维复Banach空间X上有界线性算子全体组成的Banach代数。研究了B( X)上双边保持值域(或核)包含关系的可加满射。设φ是B( X)上双边保持值域(或核)包含关系的可加满射,则存在X上的可逆有界线性或者共轭线性算子U和V使得橙T∈B( X),有φ( T)=UTV。

关 键 词:值域    包含关系  可加映射

Abstract:Let B( X) be the Banach algebra of all bounded linear operators on an infinite dimensional complex Banach space X.We consider additive surjective maps preserving operators range or kernel inclusion in both directions.It is proved that ifφis an additive surjective map on B( X) preserving operators range or kernel inclusion in both directions, then there exist invertible bounded linear or conjugate linear operators U and V on X such that for every T∈B(X),φ( T)=UTV.
Keywords:range  kernel  inclusion  additive maps
