Rank 1 forms, closed zones and laminae
Michel Marie Deza, Viatcheslav Grishukhin · Journal de Théorie des Nombres de Bordeaux · 2002
For a given lattice, we establish an equivalence between closed zones for the corresponding Voronoï polytope, suitable hyperplane sections of the corresponding Delaunay partition, and rank 1 quadratic forms which are extreme rays for the corresponding L -type domain.
