Orthogonally -Jensen mappings on -modules
Ali Zamani
We investigate the representation of the so-called orthogonally -Jensen mappings acting on -modules. More precisely, let be a unital -algebra with the u…
Norm-parallelism and the Davis--Wielandt radius of Hilbert space operators
A. Zamani, M. S. Moslehian, M. T. Chien +1
We present a necessary and sufficient condition for the norm-parallelism of bounded linear operators on a Hilbert space. We also give a characterization of the Birkhoff--James orth…
Numerical radius parallelism of Hilbert space operators
Marzieh Mehrazin, Maryam Amyari, Ali Zamani
In this paper, we introduce a new type of parallelism for bounded linear operators on a Hilbert space based on numerical radiu…
Characterizations of norm--parallelism in spaces of continuous functions
Ali Zamani
In this paper, we consider the characterization of norm--parallelism problem in some classical Banach spaces. In particular, for two continuous functions on a compact Hausdo…
Characterization of numerical radius parallelism in -algebras
Ali Zamani
Let be the numerical radius of an element in a -algebra . First, we prove several numerical radius inequalities in . Particularly, we pr…
