corresponding to the stable set. Because of the fact that S is stable, for any ij ∈ E, we have either (χ)i or (χ)j is 0, so xij = 0 whenever ij ∈ E. Then, it’s clear that I •X = 1, since X has a 1 |S| on the diagonal for each xii with i ∈ S. Finally, since X is an outer product, we have that X 0, so X is feasible for (P) with value |S|. • For the right hand inequality, we’ll use the second form...
