Orthogonality Hilbert A-modules and operators preserving multi-A-linearity
Pawel Wojcik, Ali Zamani
In this paper we present results concerning orthogonality in Hilbert -modules. Moreover, for a -algebra , we prove theorems concerning the multi-$\mathscr{A}…
From norm derivatives to orthogonalities in Hilbert -modules
Pawel Wojcik, Ali Zamani
Let be a Hilbert -module over a -algebra and let be the set of states on $\ma…
Numerical radius orthogonality in -algebras
Ali Zamani, Pawel Wojcik
In this paper we characterize the Birkhoff--James orthogonality with respect to the numerical radius norm in -algebras. More precisely, for two elements in a…
Approximately angle preserving mappings
Mohammad Sal Moslehian, Ali Zamani, Paweł Wójcik
In this paper, we present some characterizations of linear mappings, which preserve vectors at a specific angle. We introduce the concept of -angle preserving map…
Orthogonality and parallelism of operators on various Banach spaces
T. Bottazzi, C. Conde, M. S. Moslehian +2
We present some properties of orthogonality and relate them with support disjoint and norm inequalities in p Schatten ideals. In addition, we investigate the problem of characteriz…
