Face numbers of barycentric subdivisions of cubical complexes

چکیده
The h-polynomial of the barycentric subdivision any n-dimensional cubical complex with nonnegative h-vector is shown to have only real roots and be interlaced by Eulerian polynomial type Bn. This result applies subdivisions shellable complexes and, in particular, convex polytopes answers affirmatively a question Brenti, Mohammadi Welker.

On Face Vectors of Barycentric Subdivisions of Manifolds
We study face vectors of barycentric subdivisions of simplicial homology manifolds. Recently, Kubitzke and Nevo proved that the g-vector of the barycentric subdivision of a Cohen–Macaulay simplicial complex is an M -vector, which in particular proves the g-conjecture for barycentric subdivisions of simplicial homology spheres. In this paper, we prove an analogue of this result for Buchsbaum sim...
متن کاملDual Complexes of Cubical Subdivisions of R n ∗
We use a distortion to define the dual complex of a cubical subdivision of R as an n-dimensional subcomplex of the nerve of the set of n-cubes. Motivated by the topological analysis of high-dimensional digital image data, we consider such subdivisions defined by generalizations of quadand oct-trees to n dimensions. Assuming the subdivision is balanced, we show that mapping each vertex to the ce...

متن کاملThe Lefschetz Property for Barycentric Subdivisions of Shellable Complexes
We show that an ’almost strong Lefschetz’ property holds for the barycentric subdivision of a shellable complex. From this we conclude that for the barycentric subdivision of a CohenMacaulay complex, the h-vector is unimodal, peaks in its middle degree (one of them if the dimension of the complex is even), and that its g-vector is an M -sequence. In particular, the (combinatorial) g-conjecture ...
متن کاملf-VECTORS OF BARYCENTRIC SUBDIVISIONS
For a simplicial complex or more generally Boolean cell complex ∆ we study the behavior of the f and h-vector under barycentric subdivision. We show that if ∆ has a non-negative h-vector then the h-polynomial of its barycentric subdivision has only simple and real zeros. As a consequence this implies a strong version of the Charney-Davis conjecture for spheres that are the subdivision of a Bool...
