带对角线杂质的多米诺骨牌

Domino tilings with diagonal impurities

Fumihiko Nakano, Taizo Sadahiro

摘要:

本文研究了正方形-八边形格子对偶图上的二聚体模型,在某种意义上可以看作是含有杂质的多米诺骨牌。特别地,在一定的边界条件下,我们给出了一个精确的公式表示的概率发现一个杂质在一个给定的位置在一个均匀的随机二聚体配置的简单的随机游动的正方形晶格。

英文摘要:

This paper studies the dimer model on the dual graph of the square-octagon lattice, which can be viewed as the domino tilings with impurities in some sense. In particular, under a certain boundary condition, we give an exact formula representing the probability of finding an impurity at a given site in a uniformly random dimer configuration in terms of simple random walks on the square lattice.
