Study of the property (bz) using local spectral theory methods
For a bounded linear operator, by local spectral theory methods, we study the property (bz),

The property and local spectral theory
In this paper, we introduce and study the spectral property $(E_A) $. This property means
that the difference between the approximate point spectrum and the upper semi-Fredholm …
