| Nov 8, 2016 at 14:11 | comment | added | gerw | Thank you again for your changes! I still do not see how this is contained in the paper, but your answer is very clear. Just to be sure: do I get it correctly, that the existence of positive weights is equivalent to the existence of a convex lifting? | |
