组合学中的群胚--局部对称性理论的应用

Groupoids in combinatorics -- applications of a theory of local symmetries

Rade T. Zivaljevic

摘要:

组合群胚理论的一个目标是在单纯(多面体)复形、偏序集、图、多面体、排列和其他组合对象的上下文中引入诸如“完整性”、“平行输运”、“丛”、“组合曲率”等概念。在本文中,我们给出了一些目前最活跃的研究主题在这一领域的阐述,提供了一个统一的观点,并提供了一个列表,在其他领域的应用前景,以及相关的开放问题的集合。

英文摘要:

An objective of the theory of combinatorial groupoids is to introduce concepts like "holonomy", "parallel transport", "bundles", "combinatorial curvature" etc. in the context of simplicial (polyhedral) complexes, posets, graphs, polytopes, arrangements and other combinatorial objects. In this paper we give an exposition of some of the currently most active research themes in this area, offer a unified point of view, and provide a list of prospective applications in other fields together with a collection of related open problems.
