On local spectral properties of operator matrices
Abstract In this paper, we focus on a 2 × 2 $2 \times 2$ operator matrix T ϵ k $T_{\epsilon _{k}}$ as follows: T ϵ k = ( A C ϵ k D B ) , $$\begin{aligned} T_{\epsilon _{k}}= \begin{pmatrix} A & C \\ \epsilon _{k} D & B\end{pmatrix}, \end{aligned}$$ where ϵ k $\epsilon _{k}$ is a positive seq...
