带共线孔洞六边形镶嵌数比的三个乘积公式

Three product formulas for ratios of tiling counts of hexagons with collinear holes

Seok Hyun Byun

摘要:

罗森格伦发现了一个明确的公式,一定的加权枚举菱形平铺的六边形与任意三角形孔。他指出,一定的比例对应两个这样的区域有一个很好的产品公式。在本文中,我们推广到六边形与任意共线孔。事实证明,通过使用相同的方法,我们也可以推广Ciucu的工作的数量和数量的中心对称平铺的六边形与蕨类植物从其中心。这证明了Ciucu最近的一个猜想。

英文摘要:

Rosengren found an explicit formula for a certain weighted enumeration of lozenge tilings of a hexagon with an arbitrary triangular hole. He pointed out that a certain ratio corresponding to two such regions has a nice product formula. In this paper, we generalize this to hexagons with arbitrary collinear holes. It turns out that, by using same approach, we can also generalize Ciucu's work on the number and the number of centrally symmetric tilings of a hexagon with a fern removed from its center. This proves a recent conjecture of Ciucu.
