具有相同宇称的所有峰高的Dyck路的双射

Bijections for Dyck paths with all peak heights of the same parity

David Callan

摘要:

我们双射地证明了所有峰都在奇数高度的Dyck路径由Motzkin数计数,所有峰都在偶数高度的Dyck路径由Riordan数计数。

英文摘要:

We show bijectively that Dyck paths with all peaks at odd height are counted by the Motzkin numbers and Dyck paths with all peaks at even height are counted by the Riordan numbers.
