Operator Valued Maps on Hilbert -Modules
Mohammad B. Asadi, Reza Behmani, Ali R. Medghalchi +1
We provide a characterization for operator valued completely bounded linear maps on Hilbert -modules in terms of -maps. Also, we show that for every operator valued complet…
On the extendability of some classes of maps on Hilbert -modules
Mohammad B. Asadi, Reza Behmani, Ali R. Medghalchi +1
In this paper, we show that every completely semi--map on a submodule of a Hilbert -module has a completely semi--map extension on the whole of module. We also investiga…
Completely semi--maps
Mohammad B. Asadi, Reza Behmani, Ali R. Medghalchi +1
We introduce completely semi--maps on Hilbert -modules as a generalization of -maps. This class of maps provides examples of CP-extendable maps which are not CP-H-extend…
Spectral radius, numerical radius, and the product of operators
Rahim Alizadeh, Mohammad B. Asadi, Che-Man Cheng +2
Let , and denote the spectrum, spectral radius and numerical radius of a bounded linear operator on a Hilbert space , respectively. We show that a linear…
