Elnitksy多边形中的强制周长

Forced perimeter in Elnitksy polygons

Bridget Eileen Tenner

摘要:

我们研究基于平铺的周长和特征时,一个给定的周长瓷砖出现在所有菱形平铺的Elnitsky多边形。不管这个瓦片出现在周边的什么地方,它的受力都可以用321个图案来描述。我们的置换与最大许多强制的右周边瓷砖的特点,并表明,他们列举的加泰罗尼亚数。

英文摘要:

We study tiling-based perimeter and characterize when a given perimeter tile appears in all rhombic tilings of an Elnitsky polygon. Regardless of where on the perimeter this tile appears, its forcing can be described in terms of 321-patterns. We characterize the permutations with maximally many forced right-perimeter tiles, and show that they are enumerated by the Catalan numbers.
