Orthogonality Hilbert A-modules and operators preserving multi-A-linearity

Pawel Wojcik, Ali Zamani

In this paper we present results concerning orthogonality in Hilbert $C^{*}$ -modules. Moreover, for a $C^{*}$ -algebra $A$ , we prove theorems concerning the multi-$\mathscr{A}…

From norm derivatives to orthogonalities in Hilbert $C^{*}$ -modules

Pawel Wojcik, Ali Zamani

Let $(X, ⟨ \cdot, \cdot ⟩)$ be a Hilbert $C^{*}$ -module over a $C^{*}$ -algebra $A$ and let $S (A)$ be the set of states on $\ma…
