" An Interpolation Problem for Completely Positive Maps on Matrices. II"
Abstract: In this second part of our seminar talk, we explain the idea of density matrices associated to linear functionals on $*$-subspaces of matrices, that was inspired by the Smith-Ward linear functional and Arveson's Hahn-Banach type Theorem. Then we talk about the intricate relation between the positivity of the density matrix and the positivity of the corresponding linear functional.
