N1 - Part of the Lecture Notes in Mathematics book series (LNM, volume 1432) We have now shown that every non-zero degree below deg (G) coincides with deg( G ρ) for some ρ ε Π n. Since all of the positive requirements have been satisfied, we see that the lattice Π n has been embedded as an initial segment of the Δ wtt-degrees above a minimal degree.
