Subdivisions of Simplicial Complexes … NettetWe call a finite lattice crosscut-simplicial if the crosscut complex of every atomic interval is equal to the boundary of a simplex. Every interval of such a lattice is either contractible or homotopy equivalent to a sphere. Recently, Hersh and Mészáros introduced SB-labellings and proved that if a lattice has an SB-labelling then it is crosscut-simplicial. Some …

Nettet1. Simplicial sets We shall now introduce the notion of a simplicial set, which will be a presheaf on a suitable category. It turns out that simplicial sets provide a (purely combinatorial) model for the homo-topy theory of CW complexes, although we shall not prove this here.

NettetA simplicial complex is determined either by its nonfaces or by its faces. The monomials corresponding to the nonfaces are a basis of an ideal, called the Stanley-Reisner ideal, and it suffices to specify the minimal nonfaces, which generate the ideal. The monomials corresponding to the faces do not form the basis of an ideal, but it suffices ... In mathematics, a simplicial complex is a set composed of points, line segments, triangles, and their n-dimensional counterparts (see illustration). Simplicial complexes should not be confused with the more abstract notion of a simplicial set appearing in modern simplicial homotopy theory. The purely combinatorial counterpart to a simplicial complex is an abstract simplicial complex.

"NettetThe join of simplexes A and B will be denoted A⋆B, this being meaningful only when all the vertices of A and B are independent. Observe that ∅⋆A = A. The join of simplicial complexes K and L, written K⋆L, is {A⋆B : A ∈ K,B ∈ L}, where it is assumed that, for A ∈ K and B ∈ L, the vertices of A and B are independent.

Nettet5. apr. 2024 · In topological data analysis, the Vietoris-Rips filtration (sometimes shortened to "Rips filtration") is the collection of nested Vietoris-Rips complexes on a metric space created by taking the sequence of Vietoris-Rips complexes over an increasing scale parameter. Often, the Vietoris-Rips filtration is used to create a discrete, simplicial … NettetYou probably already know of many examples of simplicial complexes.
