EXTENDABLE SHELLING, SIMPLICIAL AND TORIC $h$-VECTOR OF SOME POLYTOPESDusko JojicPrirodno-matematicki fakultet, 78000 Banja Luka, Bosnia and HerzegovinaAbstract: 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. Keywords: extendable shellability; hypersimplex; toric $h$-vector Classification (MSC2000): 52B22; 52B05 Full text of the article: (for faster download, first choose a mirror)
