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 …

In this work, we present for the first time an in-depth study of the relationship between the
upper semi-B-Fredholm spectrum and the left Drazin spectrum. This connection leads to the …
