An extension of the $ρ$ -operator radii

Fuad Kittaneh, Ali Zamani

We define a function on the $C^{*}$ -algebra of all bounded linear Hilbert space operators, which generalizes the operator radii, and we present some basic properties of this fun…

Characterizations of $w_{ρ}$ -Birkhoff--James orthogonality and $w_{ρ}$ -parallelism

Fuad Kittaneh, Ali Zamani

We study the concepts of Birkhoff--James orthogonality and parallelism in Hilbert space operators, induced by the operator radius norm $w_{ρ} (\cdot)$ . In particular, we completely ch…
