$A$ -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…

C*-module operators which satisfy in the generalized Cauchy--Schwarz type inequality

Ali Zamani

Let $L (H)$ denote the $C^{*}$ -algebra of adjointable operators on a Hilbert $C^{*}$ -module $H$ . We introduce the generalized Cauchy-Schwarz inequality for…
