چکیده

Abstract A triangulation of a simplicial complex $\Delta $ is said to be uniform if the $f$-vector its restriction face depends only on dimension that face. This paper proves entries $h$-vector can expressed as nonnegative integer linear combinations those $, where coefficients depend and $f$-vectors restrictions simplices various dimensions. Furthermore, it provides information about these coefficients, including formulas, recurrence relations, interpretations, gives criterion for $h$-polynomial real rooted. These results unify generalize several in literature special types triangulations, such barycentric, edgewise interval subdivisions.

Tchebyshev triangulations of stable simplicial complexes

We generalize the notion of the Tchebyshev transform of a graded poset to a triangulation of an arbitrary simplicial complex in such a way that, at the level of the associated F -polynomials ∑ j fj−1((x − 1)/2), the triangulation induces taking the Tchebyshev transform of the first kind. We also present a related multiset of simplicial complexes whose association induces taking the Tchebyshev t...

Face enumeration on simplicial complexes

Let M be a closed triangulable manifold, and let ∆ be a triangulation of M. What is the smallest number of vertices that ∆ can have? How big or small can the number of edges of ∆ be as a function of the number of vertices? More generally, what are the possible face numbers ( f -numbers, for short) that ∆ can have? In other words, what restrictions does the topology of M place on the possible f ...

Face rings of simplicial complexes with singularities

The face ring of a simplicial complex modulo m generic linear forms is shown to have finite local cohomology if and only if the link of every face of dimension m or more is nonsingular, i.e., has the homology of a wedge of spheres of the expected dimension. This is derived from an enumerative result for local cohomology of face rings modulo generic linear forms, as compared with local cohomolog...

Triangulations of Simplicial Polytopes

Various facts about triangulations of simplicial polytopes, particularly those pertaining to the equality case in the generalized lower bound conjecture, are collected together here. They include an apparently weaker restriction on the kind of triangulation which needs to be found, and an inductive argument which reduces the number of cases to be established.

Let A be a (d + 1) d real matrix whose row vectors positively span R d and which is generic in the sense of BB arr any and Scarf BS]. Such a matrix determines a certain innnite d-dimensional simpli-cial complex , as described by BB arr any, Howe and Scarf BHS]. The group Z d acts on with nitely many orbits.
