Co-EP Banach algebra elements [PDF]

open access: yesBanach Journal of Mathematical Analysis, 2015
[EN] In this work, given a unital Banach algebra A and a \in A such that a has a Moore-Penrose inverse a^+, it will be characterized when a^+ a - a a^+ is invertible. A particular subset of this class of objects wil also be studied.

On odd duals of a Banach algebra as a Banach algebra

2022
Summary: It is known that even duals of a Banach algebra \(A\) with one of Arens products are Banach algebras, these products are natural multiplications extending the one on \(A\). But the essence of \(A^\ast\) is completely different. By defining new products, we investigate some algebraic and spectral properties of odd duals of~$A$.
