从一个Banach代数的一个子空间E到另一个Banach代数的线性映射T称为谱有界的,如果存在一个常数M>0使得对所有x∈E,r(Tx)<MR(X),其中r(.)表示光谱半径。我们证明了从单位纯无限单C*-代数到单位半单Banach代数的每个谱有界的单位算子都是Jordan满同态。
A linear mapping T from a subspace E of a Banach algebra into another Banach algebra is called spectrally bounded if there is a constant M > 0 such that r(Tx) < Mr(x) for all x ∈ E, where r(.) denotes the spectral radius. We prove that every spectrally bounded unital operator from a unital purely infinite simple C*-algebra onto a unital semisimple Banach algebra is a Jordan epimorphism.
