演讲厅隔墙的多面体几何形状

Polyhedral geometry for lecture hall partitions

McCabe Olsen

摘要:

演讲厅隔墙是一种基本的组合结构,在过去的二十年里得到了广泛的研究。这些对象产生了新的结果,以及reinterpretation和概括的经典结果,这是感兴趣的组合数论,枚举组合学和凸几何。在Savage \cite{Savage-LHP-Survey}最近的一项调查中,很好地呈现了各种各样的结果。然而,自从出版本调查,有许多新的发展有关的多面体几何和Ehrhart理论所产生的演讲厅分区。随后,在这篇调查文章中,我们专门专注于多面体几何结果的理论演讲厅分区,努力展示这些新的发展。特别是,我们强调演讲厅锥,演讲厅单纯形,演讲厅秩序多面体的结果。最后,我们在这方面的开放的问题和profetures的广泛的列表。

英文摘要:

Lecture hall partitions are a fundamental combinatorial structure which have been studied extensively over the past two decades. These objects have produced new results, as well as reinterpretations and generalizations of classicial results, which are of interest in combinatorial number theory, enumerative combinatorics, and convex geometry. In a recent survey of Savage \cite{Savage-LHP-Survey}, a wide variety of these results are nicely presented. However, since the publication of this survey, there have been many new developments related to the polyhedral geometry and Ehrhart theory arising from lecture hall partitions. Subsequently, in this survey article, we focus exclusively on the polyhedral geometric results in the theory of lecture hall partitions in an effort to showcase these new developments. In particular, we highlight results on lecture hall cones, lecture hall simplices, and lecture hall order polytopes. We conclude with an extensive list of open problems and conjectures in this area.
