For a bounded linear operator, by local spectral theory methods, we study the property (bz),
which means that the difference of the approximate point spectrum with the upper semi …

In this article, a-Browder's classical theorem is considered through the property (B v), and we
show that if two operators are norm equivalent, then property (B v) holds for one if and only if …

For bounded linear operators defined on complex infinite-dimensional Banach space, H.
Zariouh, in an article introduced and studied the property (gaz). In this study, through …

In this article, for a bounded linear operator defined on a complex infinite-dimensional
Banach space, through classical methods of local spectral theory, we study an important …

Given a complex Banach space X, we investigate the stable character of the property (VE)
for a bounded linear operator T: X→ X, under commuting perturbations that are Riesz …

In this paper, We prove some results for Drazin inverse of Lambert conditional operators,
denoted by T^ d T d, on L^ 2 (Σ) L 2 (Σ). Also we introduce some new classes of operators …

Let A be a unital primitive C∗-algebra. This article studies the properties of the B-Fredholm
elements, the B-Weyl elements and the B-Browder elements in A. Particularly, this article …

In this paper, we first calculate the measure theoretic Duggal transform of Lambert
conditional operators. Next, by using the polar decomposition of operators, we obtain Moore …
