The operator--valued parallelism and norm-parallelism in matrices
M. Mohammadi Gohari, M. Amyari
Let be a Hilbert space, and let be the -algebra of compact operators on . In this paper, we present some characterizations of the n…
Parallelism in Hilbert -modules
M. Mohammadi Gohari, M. Amyari
Let be a Hilbert space and be the -algebra of compact operators on . In this paper, we present some characteriza…
A new type of Numerical radius of operators on Hilbert -module
Marzieh Mehrazin, Maryam Amyari, Mohsen Erfanian Omidvar
In this paper, we define a new concept of numerical range and prove its basic results. We also define the numerical radius and prove that $$ω_{o}(T)\l…
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…
