An operator $ T $ acting on a Banach space $ X $ possesses property $({\rm gw}) $ if
$\sigma _a (T)\setminus\sigma _ {{\rm SBF} _+^-}(T)= E (T), $ where $\sigma _a (T) $ is the …

In this paper we introduce and study the new properties ($ W_ {\Pi} $),($ UW_ {{\Pi} _a} $),($
UW_E $) and ($ UW_ {\Pi} $). The main goal of this paper is to study relationship between …

A bounded linear operator T acting on a Banach space possesses property (gaw) if σ (T)<
Ea (T)= σBW (T), where σBW (T) is the B-Weyl spectrum of T, σ (T) is the usual spectrum of T …

In this article, we consider Drazin invertible operators for study of the relationship between
their B-Fredholm spectra and the transfer between some of the spectral properties defined …

We characterize the property (W_E) in terms of topological uniform descent, and give the
transfer of property (W_E) from bounded linear operators to functions of operators …

An operator T acting on a Banach space X satisfies the property (aw) if, where is the Weyl
spectrum of T and is the set of all eigenvalues of T of finite multiplicity that are isolated in the …

In [4] we introduced and studied property (gw), which is an extension to the context of B-
Fredholm theory, of the property (w) introduced by Rako cevic in [28]. In this paper we …
