单纯多面体的r-堆叠性概念是由McMullen和Walkup在1971年引入的,作为堆叠多面体的推广。本文定义了三角化同调流形的r-stackedness,并研究了它的基本性质。另外,当所有顶点链都是多面体时,我们得到了三角剖分流形的面向量的一个新的必要条件。
The notion of r-stackedness for simplicial polytopes was introduced by McMullen and Walkup in 1971 as a generalization of stacked polytopes. In this paper, we define the r-stackedness for triangulated homology manifolds and study its basic properties. In addition, we find a new necessary condition for face vectors of triangulated manifolds when all the vertex links are polytopal.
