The convex roof: learning by doing
What is it about?
It is a work explaining in detail how the technique to come close or even obtain the convex roof for a given entanglement measure in a density matrix of rank two. It takes some emphasis on special decompositions of the density matrix, which in certain cases become optimal.
Why is it important?
It is an important step towards a better understanding of how the convex roof construction will work for a density matrix of rank two with a glimpse also on higher rank: there we have the same convex structure behind which might involve similar solutions.
