Abstract

In this note, we study common local spectral properties for bounded linear operators AL(X,Y)A\in\mathcal{L}(X,Y) and B,CL(Y,X)B,C\in\mathcal{L}(Y,X) such that A(BA)2=ABACA=ACABA=(AC)2A.A(BA)^2=ABACA=ACABA=(AC)^2A. We prove that ACAC and BABA share the single valued extension property, the Bishop property (β)(\beta), the property (βϵ)(\beta_{\epsilon}), the decomposition property (δ)(\delta) and decomposability. Closedness of analytic core and quasinilpotent part are also investigated. Some applications to Fredholm operators are given.
