A note on the common spectral properties for bounded linear operators

Hassane Zguitti

Let $X$ and $Y$ be Banach spaces, $A : X \to Y$ and $B, C : Y \to X$ be bounded linear operators. We prove that if $A (B A)^{2} = A B A C A = A C A B A = (A C)^{2} A,$ then $$σ_{*}(AC…

Further common local spectral properties for bounded linear operators

Hassane Zguitti

In this note, we study common local spectral properties for bounded linear operators $A \in L (X, Y)$ and $B, C \in L (Y, X)$ such that $A (B A)^{2} = A B A C A = A C A B A = (A C)^{2} A .$ …
