... from the beginning of this proof. Thus, in either case x is locally equivalent to y, and the theorem is proved. ✷ PROOFOFTHEOREM2. The proof below exactly follows the proof of Proposition 5.1 ... Lemma now means simply that X corresponds to an independent set of vertices of H. Let n be even, n =2m.DenotebyH i the set of vectors of weight i: those having exactly i coordinates equ...

... bijection between sets of w minimally dependent vectors among the columns of H and (q − 1)-tuples of vectors of weight w in V , where a tuple consists of all nonzero multiples of a weight w vector. Since ... GF(q) n that contain at most j(q −1) vectors of weight w and no nonzero vectors of less weight. Since this is a downset in the poset of subspaces of GF(q) n ,...

... h ∗ -vectors as well as the proof of Theorem 1.3. The notion of triangulation of a polytope P we will use does not require that all vertices of the triangulation are necessarily vertices of P ... that ∆ is a triangulation of a polytopal complex F if the union of the faces of ∆ is equal to the union of the faces of F and every face of ∆ is contained in a face of F.In...
