Nathaniel Johnston, Erling Størmer
We investigate the relationship between mapping cones and matrix ordered *-vector spaces (i.e., abstract operator systems). We show that to every mapping cone there is an associate…

Tensor products of positive maps of matrix algebras
Erling Størmer
We give conditions for when the tensor product of two positive maps between matrix algebras is a positive map. This happens when one map belongs to a symmetric mapping cone and the…
