有界线性算子及其函数的a-Browder定理

A-Browder theorem for bounded linear operators and their functions

    摘要
  • 摘要: 文章重点研究了Weyl型定理中的a-Browder定理, 通过借助新的谱集, 给出了有界线性算子及其函数满足a-Browder定理的充要条件.

     

    Abstract: This paper focuses on a-Browder theorem, and using the new spectrum, we obtain the necessary and sufficient conditions for linear bounded operators and their functions for which obeys a-Browder theorem.
