Stable subspaces of positive maps of matrix algebras

M Miller, R Olkiewicz - Open Systems & Information Dynamics, 2015 - World Scientific
We study stable subspaces of positive extremal maps of finite dimensional matrix algebras
that preserve trace and matrix identity (so-called bistochastic maps). We have established …

Extremal Positive Maps on M3(ℂ) and Idempotent Matrices

M Miller, R Olkiewicz - Open Systems & Information Dynamics, 2016 - World Scientific
A new method of analysing positive bistochastic maps on the algebra of complex matrices M
3 has been proposed. By identifying the set of such maps with a convex set of linear …
