Simplicial Shellable Spheres via Combinatorial Blowups
The construction of the Bier sphere Bier(K) for a simplicial complex K is due to Bier (1992). Björner, Paffenholz, Sjöstrand and Ziegler (2005) generalize this construction to obtain a Bier poset Bier(P, I) from any bounded poset P and any proper ideal I ⊆ P . They show shellability of Bier(P, I) for the case P = Bn, the boolean lattice, and thereby obtain ‘many shellable spheres’ in the sense ...
متن کاملCombinatorial Properties of the K3 Surface: Simplicial Blowups and Slicings
The 4-dimensional abstract Kummer variety K4 with 16 nodes leads to the K3 surface by resolving the 16 singularities. Here we present a simplicial realization of this minimal resolution. Starting with the minimal 16-vertex triangulation (K)16 we resolve its 16 isolated singularities – step by step – by simplicial blowups. A key step is the construction of a triangulated version of the mapping c...
متن کاملSome combinatorial properties of flag simplicial pseudomanifolds and spheres
A simplicial complex ∆ is called flag if all minimal nonfaces of ∆ have at most two elements. The following are proved: First, if ∆ is a flag simplicial pseudomanifold of dimension d− 1, then the graph of ∆ (i) is (2d−2)-vertex-connected and (ii) has a subgraph which is a subdivision of the graph of the d-dimensional cross-polytope. Second, the h-vector of a flag simplicial homology sphere ∆ of...
متن کاملNew methods for constructing shellable simplicial complexes
A clutter $mathcal{C}$ with vertex set $[n]$ is an antichain of subsets of $[n]$, called circuits, covering all vertices. The clutter is $d$-uniform if all of its circuits have the same cardinality $d$. If $mathbb{K}$ is a field, then there is a one-to-one correspondence between clutters on $V$ and square-free monomial ideals in $mathbb{K}[x_1,ldots,x_n]$ as follows: To each clutter $mathcal{C}...
متن کاملOn stellated spheres, shellable balls, lower bounds and a combinatorial criterion for tightness
We introduce the k-stellated (combinatorial) spheres and compare and contrast them with kstacked (triangulated) spheres. It is shown that for d ≥ 2k, any k-stellated sphere of dimension d bounds a unique and canonically defined k-stacked ball. In parallel, any k-stacked polytopal sphere of dimension d ≥ 2k bounds a unique and canonically defined k-stacked (polytopal) ball, which answers a quest...
