On the origin of non-decomposable maps
Majewski, W. A.
Original · EN
The Radon-Nikodym formalism is used to study the structure of the set of positive maps from B(H) into itself, where H is a finite dimensional Hilbert space. In particular, this formalism was employed to formulate simple criteria which ensure that certain maps are non decomposable. In that way, a recipe for construction of non decomposable maps was obtained.
