Operator Algebras 2020-06-23 v1

Abstract

This article contains a characterization of operator systems \cS\cS with the property that every positive map ϕ:\cSMn\phi:\cS \rightarrow M_n is decomposable, as well as an alternate and a more direct proof of a characterization of decomposable maps due to E. St\o rmer.
