数值半群、多面体和偏序集II：确定某些半群族的位置
Numerical semigroups, polyhedra, and posets II: locating certain families of semigroups
摘要：
最近的几篇论文研究了一个有理多面体$P_m$，它的整数点与包含$m$的数值半群（上有限的，非负整数的可加闭子集）成双射.最近引入了$P_m$的面的一种组合描述，它可以从给定面所包含的数值半群的可除偏序集得到。在本文中，我们研究了$P_m$的面包含算术数值半群和那些包含某些胶合数值半群，作为第一步，更好地了解全面结构的$P_m$。在大多数情况下，这样的面只包含来自这些族的半群，产生与$P_m$几何的紧密连接。
英文摘要：
Several recent papers have examined a rational polyhedron $P_m$ whose integer points are in bijection with the numerical semigroups (cofinite, additively closed subsets of the non-negative integers) containing $m$. A combinatorial description of the faces of $P_m$ was recently introduced, one that can be obtained from the divisibility posets of the numerical semigroups a given face contains. In this paper, we study the faces of $P_m$ containing arithmetical numerical semigroups and those containing certain glued numerical semigroups, as an initial step towards better understanding the full face structure of $P_m$. In most cases, such faces only contain semigroups from these families, yielding a tight connection to the geometry of $P_m$.
