摘要

对于堆叠单纯形复合体(其特殊子类有:树、多边形的三角剖分、堆叠多面体及其三角剖分),我们给出了面的分割(对于树:边)与顶点分割成独立集之间的明确双射。更一般地说,我们给出了部分具有最小距离(\ge s\)的面分割和部分具有最小距离(\ge s+1\)的顶点分割之间的双射。

Partitions of Vertices and Facets in Trees and Stacked Simplicial Complexes

For stacked simplicial complexes, (special subclasses of such are: trees, triangulations of polygons, stacked polytopes with their triangulations), we give an explicit bijection between partitions of facets (for trees: edges), and partitions of vertices into independent sets. More generally, we give bijections between facet partitions whose parts have minimal distance \(\ge s\) and vertex partitions whose parts have minimal distance \(\ge s+1\).
