Onion Skins in Oriented Matroid

Gerards, Bert and Hochstättler, Winfried (1993) Onion Skins in Oriented Matroid.
Technical Report , 5 p.


We generalize the following theorem to oriented matroids: Consider a polytope P and a facet F0 of P, let H denote the hyperplanes spanned by F0. Let d denote the diameter of the coskeleton of P. To each facet choose a defining inequality and let these set of inequalities Fscr be partitioned by the distance of the corresponding facets to F0 in the coskeleton of P into Fscr = cup_{i=0}^d Fscr_i. Let ilde P_i denote the polyhedron defined by the inequalities Fscr_i and set P_i := ilde P_i cup H. Then for all i<d: P_i subset P_{i+1}.
