Extremal unital completely positive normal maps [PDF]
Anilesh MohariWe study the convex set of unital completely positive normal map on a von-Neumann algebra and find a necessary and sufficient condition for an element in the convex set to be extremal. We also deal with the same problem for the convex subset which admits a faithful normal state.View original: http://arxiv.org/abs/1301.2507
