F-vectors of Pure Complexes and Pure Multicomplexes of Rank Three
Let C be a set of multisets that is closed under taking submultisets (i.e. when X ∈ C and Y ⊆ X, we have Y ∈ C); then C is a (simplicial) multicomplex. If every member of C is a set, C is a (simplicial) complex. We denote by Fi the number of multisets of cardinality i in C. When the multiset of largest cardinality has r elements, the F-vector of C is (F0, F1, . . . , Fr). A complex or multicomp...
متن کاملThe maximum diameter of pure simplicial complexes and pseudo-manifolds
A pure simplicial complex of dimension d − 1 (or a (d − 1)-complex, for short) is any family C of d-element subsets of a set V (tipycally, V = [n] := {1, . . . , n}). Elements of C are called facets of C and any subset of a facet is called a face. More precisely, a k-face is a face with k + 1 elements. Faces of dimensions 0, 1, and d − 2 are called, respectively, vertices, edges and ridges of C...
متن کاملA Note on Solid Coloring of Pure Simplicial Complexes
We establish a simple generalization of a known result in the plane. The simplices in any pure simplicial complex in R may be colored with d+1 colors so that no two simplices that share a (d−1)-facet have the same color. In R this says that any planar map all of whose faces are triangles may be 3-colored, and in R it says that tetrahedra in a collection may be “solid 4-colored” so that no two g...
متن کاملCVD of pure copper films from novel iso-ureate complexes.
We report the synthesis and characterisation of a new family of copper(i) metal precursors based around alkoxy-N,N'-di-alkyl-ureate ligands, and their subsequent application in the production of pure copper thin films. The molecular structure of the complexes bis-copper(i)(methoxy-N,N'-di-isopropylureate) (1) and bis-copper(i)(methoxy-N,N'-di-cyclohexylureate)(5) are described, as determined by...
متن کاملGraphs of Acyclic Cubical Complexes
It is well known that chordal graphs are exactly the graphs of acyclic simplicial complexes . In this note we consider the analogous class of graphs associated with acyclic cubical complexes . These graphs can be characterized among median graphs by forbidden convex subgraphs . They possess a number of properties (in analogy to chordal graphs) not shared by all median graphs . In particular , w...
