Relative Kubo-Ando Means of Completely Positive Maps

Mohsen Kian

We develop a Kubo--Ando theory on order intervals of completely positive maps. Using Arveson's Radon--Nikodym theorem as a structural tool, we define relative Kubo--Ando means \(Î¦…

Matrix-Test Duality: A Support-Function Characterization for $C^{*}$ -Convex Families of CP Maps

Mohsen Kian, Mario Krnic

We develop a matrix-test dual framework for $C^{*}$ -convex families of completely positive maps $\CP(\mathscr S,\mathscr T)$, where $S$ is an operator system and $\mathscr T…
