Duality of cones of positive maps
Erling Størmer
We study the so-called K-positive linear maps from B(L) into B(H) for finite dimensional Hilbert spaces L and H and give characterizations of the dual cone of the cone of K-positiv…
Separable states and positive maps II
Erling Stormer
Using the natural duality between linear functionals on tensor products of C*-algebras with the trace class operators on a Hilbert space H and linear maps of the C*-algebra into B(…
Asymptotic lifts of positive linear maps
William Arveson, Erling Stormer
We show that the notion of asymptotic lift generalizes naturally to normal positive maps acting on von Neumann algebras M. We focus on cases in which the domain of the asymptot…
A reduction theorem for capacity of positive maps
Erling Stormer
We prove a reduction theorem for capacity of positive maps of finite dimensional C*-algebras, thus reducing the computation of capacity to the case when the image of a nonscalar pr…
