Approximate graph colouring and the hollow shadow
We show that approximate graph colouring is not solved by constantly many levels of the liftand-project hierarchy for the combined basic linear programming and affine integer programming relaxation. The proof involves a construction of tensors whose fixed-dimensional projections are equal up to refl...
