Algebraic shifting of cyclic polytopes and stacked polytopes

Research output: Contribution to conferencePaper

Abstract

Gil Kalai introduced the shifting-theoretic upper bound relation to characterize the f-vectors of Gorenstein * complexes (or homology spheres) by using algebraic shifting. In the present paper, we study the shifting-theoretic upper bound relation. First, we will study the relation between exterior algebraic shifting and combinatorial shifting. Second, by using the relation above, we will prove that the boundary complex of cyclic polytopes satisfies the shifting theoretic upper bound relation. We also prove that the boundary complex of stacked polytopes satisfies the shifting-theoretic upper bound relation.
