$A$ -spectral permanence property for $C^{*}$ -algebras

Mohamed Mabrouk, Ali Zamani

For a positive element $A$ of a $C^{*}$ -algebra $A$ , let $∥ X ∥_{A}$ denote the $A$ -operator semi-norm of $X \in A$ . In this paper, we aim to introduce and stud…

An extension of the $a$ -numerical radius on $C^{*}$ -algebras

Mohamed Mabrouk, Ali Zamani

Let $a$ be a positive element in a unital $C^{*}$ -algebra $A$ . We define a semi-norm on $A$ , which generalizes the $a$ -operator semi-norm and the $a$ -numerical…
