用于窄矩形的直多边形镶嵌的Generating functions

Generating functions for straight polyomino tilings of narrow rectangles

Mudit Aggarwal, Samrith Ram

摘要:

设$m,k$为固定的正整数。由$k\times 1$矩形确定$m\times n$矩形的平铺数的生成函数是一个长期存在的公开问题,其答案仅在某些特殊情况下是已知的。在$m<2k$ .此结果用于获得具有$k\times k\times 1$砖的$m\times n \times k$盒的平铺数的生成函数。

英文摘要:

Let $m,k$ be fixed positive integers. Determining the generating function for the number of tilings of an $m\times n$ rectangle by $k\times 1$ rectangles is a long-standing open problem to which the answer is only known in certain special cases. We give an explicit formula for this generating function in the case where $m<2k$. This result is used to obtain the generating function for the number of tilings of an $m\times n \times k$ box with $k\times k\times 1$ bricks.
