关于算子组Taylor谱的定义

On the Definition of the Taylor's Joint Spectrum of the Tuples of Operators

给出了关于算子组Taylor谱的另一种定义及ε-联合伪谱的定义,并讨论了它的一些性质以及关于交叉交换算子组在这几种定义下的一些结果．

This paper gives another definition of the Taylor＇s joint spectrum of the tuples of operators and the definition of the the joint ε-pseudospectrum, and then discusses its some properties and some results about the criss-cross commutivity tuples of operators.
