An Interpolation Problem for Completely Positive Maps on Matrices. II
Aurelian Gheondea
Bilkent University, Türkiye
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.
