摘要:
本文给出了有界线性算子$T$为广义Drazin-Riesz可逆算子或广义Drazin-亚纯可逆算子的充要条件.利用$T$谱的各部分的内点集,研究了广义Browder定理和广义a-Browder定理.
英文摘要:
In this paper we give necessary and sufficient conditions for a bounded linear operator $T$ to be generalized Drazin-Riesz invertible or generalized Drazin-meromorphic invertible. Also, we study generalized Browder's theorem and generalized a-Browder's theorem by means of set of interior points of various parts of spectrum of $T$.
