EXTENDABLE SHELLING, SIMPLICIAL AND TORIC h-VECTOR OF SOME POLYTOPES
نویسنده
چکیده
We show that the stellar subdivisions of a simplex are extendably shellable. These polytopes appear as the facets of the dual of a hypersimplex. Using this fact, we calculate the simplicial and toric h-vector of the dual of a hypersimplex. Finally, we calculate the contribution of each shelling component to the toric h-vector.

Shelling and the h-Vector of the (Extra)ordinary Polytope
Ordinary polytopes were introduced by Bisztriczky as a (nonsimplicial) generalization of cyclic polytopes. We show that the colex order of facets of the ordinary polytope is a shelling order. This shelling shares many nice properties with the shellings of simplicial polytopes. We also give a shallow triangulation of the ordinary polytope, and show how the shelling and the triangulation are used...
متن کاملThe h-Vector of a Gorenstein Toric Ring of a Compressed Polytope
A compressed polytope is an integral convex polytope all of whose pulling triangulations are unimodular. A (q − 1)-simplex Σ each of whose vertices is a vertex of a convex polytope P is said to be a special simplex in P if each facet of P contains exactly q − 1 of the vertices of Σ. It will be proved that there is a special simplex in a compressed polytope P if (and only if) its toric ring K[P]...
متن کاملThe short toric polynomial
We introduce the short toric polynomial associated to a graded Eulerian poset. This polynomial contains the same information as Stanley’s pair of toric polynomials, but allows different algebraic manipulations. Stanley’s intertwined recurrence may be replaced by a single recurrence, in which the degree of the discarded terms is independent of the rank. A short toric variant of the formula by Ba...
متن کاملOn the Generalized Lower Bound Conjecture for Polytopes and Spheres
In 1971, McMullen and Walkup posed the following conjecture, which is called the generalized lower bound conjecture: If P is a simplicial d-polytope then its h-vector (h0, h1, . . . , hd) satisfies h0 ≤ h1 ≤ · · · ≤ h⌊ d2 ⌋. Moreover, if hr−1 = hr for some r ≤ d2 then P can be triangulated without introducing simplices of dimension ≤ d− r. The first part of the conjecture was solved by Stanley ...
متن کاملClassification of pseudo-symmetric simplicial reflexive polytopes
Gorenstein toric Fano varieties correspond to so called reflexive polytopes. If such a polytope contains a centrally symmetric pair of facets, we call the polytope, respectively the toric variety, pseudo-symmetric. Here we present a complete classification of pseudo-symmetric simplicial reflexive polytopes. This is a generalization of a result of Ewald on pseudosymmetric nonsingular toric Fano ...
