有理Dyck镶嵌

Rational Dyck tilings

Keiichi Shigechi

摘要:

我们引入理性Dyck切片或$(a,b)$ -Dyck切片,并通过分解为$(1,1)$ -Dyck切片来研究它们。这种分解使我们能够利用组合模型的$(1,1)$ -戴克瓷砖,如埃尔米特的历史和戴克瓷砖带双射。结合与有理Dyck镶嵌相关的$b$ -Stirling置换,我们得到了$(a,b)$ -Dyck镶嵌与$ab$ $(1,1)$ -Dyck镶嵌元组之间的对应关系.

英文摘要:

We introduce rational Dyck tilings, or $(a,b)$-Dyck tilings, and study them by the decomposition into $(1,1)$-Dyck tilings. This decomposition allows us to make use of combinatorial models for $(1,1)$-Dyck tilings such as the Hermite history and the Dyck tiling strip bijection. Together with $b$-Stirling permutations associated to the rational Dyck tilings, we obtain a correspondence between an $(a,b)$-Dyck tiling and a tuple of $ab$ $(1,1)$-Dyck tilings.
