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.…

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})…
