摘要
本文定义一种新的算子――NN算子,通过这种新算子定义的NN谱给出有界线性算子满足Weyl定理、a-Weyl定理、Browder定理和a-Browder定理的充要条件.
This paper defines a new operator—NN operator, and gives the sufficient and necessary conditions that satisfy Weyl＇s theorem, a-Weyl＇s theorem, a-Weyl＇s theorem, Browder＇s theorem and aBrowder＇s theorem for a bounded linear operator by means of the NN spectrum defined by the new operator.
