彩色合成、Dyck 路径与多边形剖分之间的双射

Bijections between colored compositions, Dyck paths, and polygon partitions

Juan B. Gil, Emma G. Hoover, Jessica A. Shearer

AI总结:

该研究通过识别并装饰合成、Dyck 路径与凸多边形剖分中的构建块,构造了保持部分且支持彩色情形的双射,从而统一刻画三类组合对象。

摘要:

本文在三类基本对象族之间给出保持部分的双射;这些对象族是许多计数组合学问题的自然框架。具体而言,我们考虑合成、Dyck 路径和凸多边形的剖分,并识别合适的构建块,随后对其进行适当装饰,以实现基数相匹配。我们的双射是构造性的,并适用于允许构建块具有不同颜色的一般情形。

英文摘要:

In this paper, we give part-preserving bijections between three fundamental families of objects that serve as natural framework for many problems in enumerative combinatorics. Specifically, we consider compositions, Dyck paths, and partitions of a convex polygon, and identify suitable building blocks that are then appropriately decorated to achieve matching cardinalities. Our bijections are constructive and apply for the general case where the building blocks are allowed to come in different colors.
