Abstract Let B (X) B (X) be the Banach algebra of all bounded linear operators on a Banach space X into itself. In this paper, we extend and simplify some results concerning the …
The spectral properties of a compact operator T: X−→ Y on a normed linear space resemble those of square matrices. For a compact operator, the spectral properties can be treated …
The introduction of Fredholm theory relative to general unital homomorphisms T: A → BT: A→ B between Banach algebras A and B, which involves the study of Fredholm, Weyl and …
In this research, we study spectral theory in ordered Banach algebras. Spectral theory in ordered Banach algebras has only been studied in the last two and half decades, and there …
