On quasinilpotent equivalence of finite rank elements in Banach algebras

We characterize elements in a semisimple Banach algebra which are quasinilpotent equivalent to maximal finite rank elements.
On rank one and finite elements of Banach algebras

We give a spectral characterisation of rank one elements and of the socle of a semisimple Banach algebra.
On rank one elements
Robin Harte (1995)

Without the "scarcity lemma", two kinds of "rank one elements" are identified in semisimple Banach algebras.

In this paper we prove that the image of a nth order derivation on real commutative Banach ℓ-algebras with positive squares is contained in the set of nilpotent elements.
