Let T be a bounded linear operator on a Banach space X. We prove certain inclusions and equalities between different parts of the spectrum of T and then apply them to study Koliha-Drazin invertible operators and operators satisfying a-Browder’s theorem.

关于 Koliha-Drazin 可逆算子和 a-Browder 定理的一个注记

T是 Banach 空间X上的一个有界线性算子。我们证明了T谱的不同部分之间的某些包含和等式,然后将它们应用于研究 Koliha-Drazin 可逆算子和满足 a-Browder 定理的算子。
