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…

Orthogonally $a$ -Jensen mappings on $C^{*}$ -modules

Ali Zamani

We investigate the representation of the so-called orthogonally $a$ -Jensen mappings acting on $C^{*}$ -modules. More precisely, let $A$ be a unital $C^{*}$ -algebra with the u…

Characterization of numerical radius parallelism in $C^{*}$ -algebras

Ali Zamani

Let $v (x)$ be the numerical radius of an element $x$ in a $C^{*}$ -algebra $A$ . First, we prove several numerical radius inequalities in $A$ . Particularly, we pr…
