Fredholm Perturbation of Spectra of $2 \times 2$ Upper Triangular Matrix

Zhang Shifang, Zhong Huaijie, Wu Junde

As we knew, study the perturbation theory of spectra of operator is a very important project in mathematics physics, in particular, in quantum mechanics. In this paper, we characte…

Spectra of Upper-triangular Operator Matrix

Zhang Shifang, Zhong Huaijie, Wu Junde

Let $X$ and $Y$ be Banach spaces, $A \in B (X)$ , $B \in B (Y)$ , $C \in B (Y, X)$ , $M_{C}=({cc}A&C 0&B)$ be the operator matrix acting on the Banach space $X \oplus Y$ . In this paper, we g…
