Orthogonality preserving property for pairs of operators on Hilbert -modules

Michael Frank, M. S. Moslehian, Ali Zamani

We investigate the orthogonality preserving property for pairs of mappings on inner product -modules extending existing results for a single orthogonality-preserving mapping.…

An extension of orthogonality relations based on norm derivatives

A. Zamani, M. S. Moslehian

We introduce the relation -orthogonality in the setting of normed spaces as an extension of some orthogonality relations based on norm derivatives, and present some of its ess…

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…

Photo-induced spin and valley-dependent Seebeck effect in the low-buckled Dirac materials

Yawar Mohammadi

Employing the Landauer-Buttiker formula we investigate the spin and valley dependence of Seebeck effect in low-buckled Dirac materials (LBDMs), whose band structure are modulated b…

Characterizations of operator Birkhoff-James orthogonality

Mohammad Sal Moslehian, Ali Zamani

In this paper, we obtain some characterizations of the (strong) Birkhoff--James orthogonality for elements of Hilbert -modules and certain elements of $\mathbb{B}(\mathscr{H})…
