Infinite dimensional analogues of Choi matrices

Kyung Hoon Han, Seung-Hyeok Kye, Erling Størmer

For a class of linear maps on a von Neumann factor, we associate two objects, bounded operators and trace class operators, both of which play the roles of Choi matrices. Each of th…

A Kirchberg type tensor theorem for operator systems

Kyung Hoon Han

We construct operator systems that are universal in the sense that all operator systems can be realized as their quotients. They satisfy the operator system lifting…

The predual of the space of decomposable maps from a -algebra into a von Neumann algebra

Kyung Hoon Han

For a -algebra and a von Neumann algebra , we describe the predual of space of decomposable maps from into $\m…

On maximal tensor products and quotient maps of operator systems

Kyung Hoon Han

We introduce quotient maps in the category of operator systems and show that the maximal tensor product is projective with respect to them. Whereas, the maximal tensor product is n…

An approximation theorem for nuclear operator systems

Kyung Hoon Han, Vern I. Paulsen

We prove that an operator system is nuclear in the category of operator systems if and only if there exist nets of unital completely positive maps $ϕ_λ: \cl S \to M_{n…

Matrix regular operator space and operator system

Kyung Hoon Han

We establish a relationship between Schreiner's matrix regular operator space and Werner's (nonunital) operator system. For a matrix ordered operator space with complete norm,…
