具有负边界的k-Dyck路

On k-Dyck paths with a negative boundary

Helmut Prodinger

摘要:

由一个单位的向上步和$k$单位的向下步组成的路径,由水平线$-t$在下面限定,表现得像$k$-Dyck路径的$t+1$有序元组,条件是$t\le k$。我们描述的一般情况下,允许$t$也更大。参数是双射的和/或分析的。

英文摘要:

Paths that consist of up-steps of one unit and down-steps of $k$ units, being bounded below by a horizontal line $-t$, behave like $t+1$ ordered tuples of $k$-Dyck paths, provided that $t\le k$. We describe the general case, allowing $t$ also to be larger. Arguments are bijective and/or analytic.
