多米诺平铺同余模4

Domino Tiling Congruence Modulo 4

Bridget Eileen Tenner

摘要:

组合示出了具有反射对称性的区域的多米诺骨牌平铺的数量取决于特定子区域的多米诺骨牌平铺的数量,模4。这扩展了以前的多米诺骨牌拼接的全等结果,模2,并导致各种推论,包括k x 2k矩形的多米诺骨牌拼接的数量是全等的1模4。

英文摘要:

The number of domino tilings of a region with reflective symmetry across a line is combinatorially shown to depend on the number of domino tilings of particular subregions, modulo 4. This expands upon previous congruency results for domino tilings, modulo 2, and leads to a variety of corollaries, including that the number of domino tilings of a k x 2k rectangle is congruent to 1 mod 4.
