Necessary Condition of Mixture Separability for the Set Split

Let s formulate now the main necessary condition of mixtures separability for the set split it is necessary that at the boundary element to which the top product 

If the split without distributed components is set, then the mentioned trajectory tear-off regions of sections should be boundary elements of one sharp split region 

Product points can belong only to those boundary elements of concentration simplex that contain trajectory tear-off regions. Along with that, product points should be located at these boundary elements within the limits of some region, 

The process of sharp distillation is feasible only if each product point belongs to
